COVID-19 vaccine

The COVID-19 vaccine is a type of vaccine that immunizes patients to the disease COVID-19, caused by the virus SARS-CoV-2. During their first year, they saved almost 20 million lives. Nonetheless, there are many concerns about the new coronavirus vaccine scaremongering about its safety and effectiveness. This article seeks to refute and dispel those myths.

=== Omicron and boosters ===
In November 2021, a heavily mutated strain was discovered in South Africa. Despite many travel restrictions being put in place, the Omicron variant quickly spread across the world, becoming the dominant strain in many countries. This variant has proven to be far more transmissible than Delta and is capable of evading vaccines. The UK Health Security Agency found that two doses of the Pfizer, Moderna or AstraZeneca vaccine provided little protection against infection.https://www.independent.co.uk/news/health/omicron-variant-booster-effectiveness-covid-b1973868.html However, two doses are still thought to provide good protection against severe illness.https://www.cdc.gov/coronavirus/2019-ncov/vaccines/effectiveness/work.html
As a result, booster vaccines became more widespread, with the UK Health Security Agency estimating that a booster jab was 70-75% effective at preventing infection. https://www.cnbc.com/2021/12/10/boosters-give-70percent-75percent-protection-against-mild-disease-from-omicron-uk-health-security-agency-says.html The CDC also recommended getting a booster, five months after receiving the Pfizer jabs, six months after receiving the Moderna jabs and two months after receiving the Johnson & Johnson jab.https://www.cdc.gov/coronavirus/2019-ncov/vaccines/booster-shot.html 
Scientific consensus therefore generally recommends two or more boosters per year for the large majority of adults and children.
==Arguments==
====The vaccine is built on experimental technology====
mRNA technology has been in the works for 20 years for other viruses;Richner JM, Himansu S, Dowd KA, Butler SL, Salazar V, Fox JM, Julander JG, Tang WW, Shresta S, Pierson TC, Ciaramella G, Diamond MS. Modified mRNA Vaccines Protect against Zika Virus Infection. Cell. 2017 Mar 9;168(6):1114-1125.e10. doi: 10.1016/j.cell.2017.02.017. it is only now that they have been put to use, and has helped us develop a vaccine in record times.The mRNA vaccine revolution is just beginning by Stephen Buranyi (3 June, 2021) WIRED 
 (Westernized name order; Hungarian name order Karikó Katalin) started her research on mRNA therapies in 1990, and, in spite of what faculty members deemed a career dead-end in a university system that encourages programs that will bring in grants, continued her work even after being demoted. She eventually met immunologist Drew Weissman, with whom she worked on the problem for a decade until they finally found a solution to the human immune system rejecting foreign, synthetic mRNA instructions—something anyone who thinks human DNA replacement is easy should stop to think about. Their solution (incorporating modified nucleosides into mRNA) was published in 2005 and was largely not paid attention to. It was, however, noticed in Germany by BioNTech founders Özlem Türeci and Ugur Sahin, and in the United States by Moderna founder Derrick Rossi. Both Moderna and Pfizer/BioNTech licensed Karikó and Weissman's research in the production of their vaccines. Pardi, N., Hogan, M., Porter, F. et al. mRNA vaccines — a new era in vaccinology.

Retrieved 8/10/2021.The story of mRNA: How a once-dismissed idea became a leading technology in the Covid vaccine race STAT, 11/10/2020. Retrieved 8/10/2021.
====Not enough research was done; they were rushed to the market====
Before the COVID-19 pandemic, there was not much need to speed up vaccination process for any pathogen. Time taken by clinical trials continued to rise even after considerable industrial effort,Martin, L., Hutchens, M. & Hawkins, C. Clinical trial cycle times continue to increase despite industry efforts. Nat Rev Drug Discov 16, 157 (2017). https://doi.org/10.1038/nrd.2017.21 often taking many months and even years. There was considerable lack of infrastructure, few consenting volunteers, absence of control groups and high waiting times between phases. Furthermore, most potential inoculations and medications failed their respective clinical trials.
However, the demand for coronavirus vaccines rose after medical health crises in many countries; leading to great investment from governments and corporations and global cooperation from scientists working day and night for a solution. Research was sped up for the development of a vaccine by overlapping different phases of the trials. It also received a significant head start with past knowledge of other coronaviruses,https://www.niaid.nih.gov/diseases-conditions/coronaviruses so it took no time to realise the spike protein could be targeted by a vaccine, giving them a goal to work towards immediately. Research on a vaccine for coronaviruses has been in development since 2002, after the SARS outbreak. Governments sent a huge influx of fundingEstimating the cost of vaccine development against epidemic infectious diseases: a cost minimisation study by Gouglas, Dimitrios et al. The Lancet Global Health, Volume 6, Issue 12, e1386 - e1396 and volunteers, while the anti-vaxx risked their lives to act as a control group for us. How nice of them!
On 10 August, the World Health Organization (WHO) listed over 110 possible vaccine candidates currently in clinical development (and 184 more in pre-clinical),The COVID-19 vaccine tracker and landscape compiles detailed information of each COVID-19 vaccine candidate in development by closely monitoring their progress through the pipeline. but it was unlikely that many of those would be approved for use. There were, however, some legitimate concerns regarding the adverse effects of too much speed, especially from the provaxx crowd,No, the rush for a COVID-19 vaccine is not turning provaccine advocates into antivaxxers after the launch of "Operation Warp Speed" under the Trump administration, which seeked to force the FDA to approve a coronavirus vaccine without any evidence of safety.
====People who have already had the virus don't need the vaccine====
Immunity acquired from vaccination has shown to be more long lasting than from an infectionhttps://www.nytimes.com/2021/06/28/health/coronavirus-vaccines-immunity.html and covers a broader range of (the part of an antigen molecule to which an antibody attaches itself), allowing vaccination to combat the newer and more advanced variants.https://stm.sciencemag.org/content/13/600/eabi9915.abstract Post-infection immunity is scattershot as the immune system tries everything and the kitchen sink against the virus in the case of infection, whereas the vaccines prime the immune system to attack the spike protein—which is how the virus attaches itself in the beginning of the infection. Vaccines aim to stop the infection in its tracks; infection-based immunity is far less reliable.No, your antibodies are not better than vaccination: An explainer by Beth Mole (October 8, 2021) Ars Technica
====People don’t need to wear a mask after getting vaccinated====
Getting vaccinated significantly reduces risk of infection and the severity of the infection. It also reduces risk of transmission, but less so. This means that vaccination will not prevent you from spreading it to other people like those with compromised immune systems—such as those with heart diseases, or those with autoimmune diseases or cancer undergoing treatment to name a few.Already Vaccinated? Here’s Why You Shouldn’t Stop Wearing Your Face Mask Yet
(March 8, 2021.) Cleveland Clinic However, it will reduce its risk.https://www.healthline.com/health-news/vaccinated-people-can-transmit-the-coronavirus-but-its-still-more-likely-if-youre-unvaccinated Of course, mask wearing would be unnecessary if everyone else around you were vaccinated.
====The vaccines have serious chronic side effects====
"Breakthrough cases" are unfortunately common,COVID-19 Vaccines are Effective Centers for Disease Control (June 22, 2022.) however, vaccines have a high efficacy of preventing severe disease that leads to hospitalization (above table). Compare that to the coronavirus, with a death toll of more than 4 million.https://www.worldometers.info/coronavirus/ 
Common side effects for the vaccines vary depending on the vaccine in question, and include:Side Effects of COVID-19 Vaccines World Health Organization (March 21, 2021.) Possible Side Effects After Getting a COVID-19 Vaccine Centers for Disease Control (August 6, 2021.)
* Pain, redness, or swelling at the injection site
* Fever
* Fatigue/tiredness
* Headache 
* Muscle pain
* Chills 
* Diarrhea
* Nausea
These side effects can last 1-3 days. Individuals should alert their local health officials if symptoms last longer than this. The second dose may come with stronger side effects—this is normal, and indicates that your body is building up immunity (and getting riled up thanks to memory cells seeing foes.How The Immune System ACTUALLY Works – IMMUNE from the [YouTube] channel Kurtzgesagt. (Retrieved August 12, 2021)Understanding the Memory of the Immune System Labroots (December 26, 2017.))
Anaphylaxis is an extremely rare side effect; but just to be on the safe side, this is why it is often asked that individuals stay at the vaccination site for 15-30 minutes. If you have had an extreme reaction to the first dose (assuming two-dose vaccine), you should not get the second one. 
Another rare side effect is myocarditis, emphasis on rare. Even for the most-at-risk group (males aged 12-29) the risk is 41 in one million, rarer than the risk of long-term COVID symptoms, or even the death rate from COVID-19.
A recent study based on vaccine surveillance data from 6.2 million people found no associations between vaccinations and serious health outcomes 1 to 21 days after vaccination.Klein NP, Lewis N, Goddard K, et al. Surveillance for Adverse Events After COVID-19 mRNA Vaccination. JAMA. Published online September 03, 2021. doi:10.1001/jama.2021.15072
====They have long term side effects====
Severe side effects from vaccines are extremely rare, and if they do occur, they usually show up within the first weeks—so not long-term. Unlike most medications, vaccines are not taken for an extended period of time. The injections (be it one to three times, per vaccine efficacy requirements) drop the payload which is eliminated by the body in a matter of months. Conversely, 10% of COVID-19 infections lead to long-term COVID side effects.| What are the long-term side effects of COVID vaccines? 3 things to know by Matt Windsor (July 1, 2021) The University of Alabama at Birmingham There is some evidence that vaccines may even help alleviate "long COVID" symptoms, to the tune of 30-40% of patients reporting improvement.| Why Vaccines May Be Helping Some With Long COVID by Kathy Katella (April 21, 2021) Yale Medicine
====They can alter DNA====
None of the vaccines’ payload ever enters the nucleus, where the DNA is kept. mRNA is translated into proteins in the not the nucleus. They use a chemical messenger to instruct cells to make proteins that mimic the outer surface of the new coronavirus, thereby creating immunity.Let’s talk about lipid nanoparticles. Nat Rev Mater 6, 99 (2021). https://doi.org/10.1038/s41578-021-00281-4
====They shed DNA====
Inactivated virus vaccines cannot shed DNA, since, well, they are inactivated, are no more, have ceased to be, are bereft of life, rest in peace, are a collection of ex-viruses, and are hence incapable of replication. The mRNA vaccines only contain instructions for making spike protein, therefore they also can’t replicate. What does shed material likely to harm one, however, is a coronavirus infection, where the spike proteins are still alive and very keen to replicate.“The vaccinated are a danger to the unvaccinated because of shedding!”: The latest COVID-19 antivaccine disinformation by David Gorski (May 3, 2021) Science-Based Medicine. As David Gorski from Science Based Medicine attests:
====They cause infertility====
This is an old urban myth spread through blogposts and social media of the anti-vaccination movement, now repackaged to stigmatise coronavirus vaccines in times of crisis to further unscientific opposition to vaccines.
Arising from the "concerns" of a German epidemiologist, that the vaccine might make women infertile because of a shared genetic code between the coronavirus spike protein and the placenta (the organ that develops in the uterus during pregnancy), which would make the immune system attack both because it can’t tell the difference, is completely irrational, as the shared genetic amino acid sequence between the two is simply too short.Are COVID-19 Vaccines Going To Cause Infertility? by Edward Nirenberg (December 3, 2020) in Deplatform Disease.
Furthermore, this risk has been continuously disproven in clinical trials. Women involved in COVID-19 clinical trials became pregnant and gave birth after getting vaccinated which demonstrates that any concern that there would be problems arising from similarities between the placenta and vaccine spike protein is unfounded. Here’s Where That COVID-19 Vaccine Infertility Myth Came From—And Why It Is Not True by Henry Ford Health System Staff (April 23, 2021) Henry Ford. The CDC has issued a recommendation that people who are pregnant and breastfeeding should get the vaccine because people within that group are more likely to develop a more severe case of COVID-19, but that is preventable if enough people get the vaccine. According to current research, there is no evidence that COVID-19 vaccines cause fertility problems for men or women.COVID-19 Vaccines While Pregnant or Breastfeeding (Updated August 11, 2021) CDC. 
However, there have been a number of studies suggesting that COVID-19 and Long COVID reduce fertility in especially men more than women but more research must be conducted to ascertain a more complete picture of the problem.Abobaker A, Raba AA. Does COVID-19 affect male fertility?. World J Urol. 2021;39(3):975-976. doi:10.1007/s00345-020-03208-w In recent studies about Long COVID, men that contracted COVID-19 reported they had erectile problems 3 times more than men in the control group when comparing men with similar ages mental physical health and BMI. 28% of men who tested positive reported erectile dysfunction problems in comparison to 9% in the control group. Infertility from COVID-19 occurs because the virus and vascular damage from the virus remains in the area after the infection occurs.New studies show evidence of Long Covid Penis Problems
by Thom Dunn (4:56 AM Thursday, 12 August, 2021) Boing Boing. To summarise: the vaccine probably won’t make you infertile; but the coronavirus will. So don’t be a dick, and get the shot.[pun not intended]
====They do not work====
Anti-vaxx proponents cite the possibility of infection even after vaccination as evidence that the coronavirus vaccine is inefficacious, ignoring the fact that vaccination does lower the chances of infection and hospitalisation after infection. The purpose of vaccination is not to reduce cases; it is to save lives. This does not necessarily mean saving the lives of those infected with COVID-19, but also others who might need ICU treatment as well—if the ICUs are full with COVID-19 patients, there's nowhere to go when one's heart is at its last.Alabama man dies of cardiac event after 43 hospitals with full ICUs turned him away by Hadley Hitson (10 Sep, 2021) for The Montgomery Advisor via USA Today
Cases where fully vaccinated individuals become infected, undergo hospitalisation or die are known as “breakthrough cases”. These are incredibly rare, but still expected, as the immune system is chaotic and no vaccines can be 100% effective.COVID-19 Vaccine Breakthrough Cases: Data from the States by Jennifer Kates, Lindsey Dawson, Emma Anderson, Anna Rouw Follow, Josh Michaud Follow, and Natalie Singer (30 Jul, 2021) KFF 
And should one say that the vaccines are useless because they're not a magic bullet that gives immunity to any and all variants till forever, bear in mind that H1N1 (often unfairly called the Spanish Flu) is still around—and deadly. It's been with us for over a hundred years, and a variation of it last caused a pandemic in 2009—and it was still far tamer than the SARS-CoV-2 virus is.| H1N1 flu (swine flu) (Retrieved 18 August, 2021) Mayo Clinic The 2009 H1N1 pandemic caused an estimated 203,000 deaths globally,| 2009 Pandemic Flu Death Toll Much Higher Than Official Worldwide Estimates (November 26, 2013) The George Washington University School of Public Health and Health Services and it may be best that we not include current global COVID-19 deaths because of how fast the number changes. (Spoiler alert: it's way more than 203,000.) 
Nowadays, H1N1 is one of the viruses/virii the seasonal flu vaccine targets. It's retooled every year in response to mutations and what various Influenza A strains are circulating through scientific consensus by global scientists. Unless you're a selfish prick, you're probably used to getting it yearly. Key Facts About Seasonal Flu Vaccine (Page last reviewed June 8, 2021) Centers for Disease Control Selecting Viruses for the Seasonal Influenza Vaccine (Page last reviewed October 26, 2020) Centers for Disease Control
As of 23 August 2021, Pfizer/BioNTech's Comirnaty has FDA approval for adults, with emergency authorization for the 12-15 age group.FDA Approves First COVID-19 Vaccine Centers for Disease Control (23 August, 2021)
====They make you magnetic====
The vaccines do not make one magnetic,The Unfiltered Truth Behind Human Magnetism, Vaccines, And COVID-19 Forbes (Jun 23, 2021.) in spite of the unfortunately aptly named Dr. Sherri Tenpenny testifying so in Ohio with a bit of failed show-and-tell later in the same session by a registered nurse who demanded the crowd for answers why a key supposedly stuck to her chest and neck.GOP-invited Ohio doctor Sherri Tenpenny falsely tells Ohio lawmakers COVID-19 shots 'magnetize' people, create 5G 'interfaces' USA Today (June 9, 2021.) We're frankly a little confused, as this is something RW used to have to explain as not real for less deadly scammy reasons.
====They contain aborted fetal cells====
This is a misconception that appeals strongly to people who are anti-abortion. Aborted fetal cells are not contained in the most popular COVID-19 vaccines, although they were used to test the vaccine. The cell line used in testing was HEK-293, which was obtained from a fetus that happened to be aborted in the 1960-1970s.Immortalized cells and one oncogene in malignant transformation: old insights on new explanation by Vadym M. Kavsan et al. (23 May 2011). BMC Cell Biol. 12:23. doi:10.1186/1471-2121-12-23 Contrary to what anti-vaxxers may claim, the purpose of the abortion was not to obtain the HEK cells. It makes absolutely zero sense to reject the COVID-19 vaccine based solely on the fact it was tested on HEK-293 cells, as almost all modern medicines have been tested on it. It's nearly impossible to avoid using pharmaceutical products that have not been tested on HEK cells – if using medicines/vaccines tested on them is "unethical", you can say goodbye to modern medicine. In fact, it is estimated that the top 20 medications prescribed in the US have been tested on HEK cell lines.If any drug tested on HEK-293 is immoral, goodbye modern medicine. by Matthew P. Schneider (January 28, 2021) Patheos.
====They clot your blood====
The cases of blood clotting have been well below the natural frequency without vaccination—that's to say, from the time before the vaccines were ready, severe cases of Covid-19 saw blood clotting in 20-40% of patients. Conversely, these blood clots have only been seen in Johnson & Johnson/Janssen and AstraZeneca vaccines—to the tune of 35 known cases in the former and 300 in the latter, and none have been reported with mRNA vaccines. For a yearly US perspective, roughly 900,000 people experience a clot and 100,000 die of one.| Blood clotting, Covid-19 and vaccines by Kylene Metzger (July 7, 2021) University of Utah Health| The Johnson & Johnson Vaccine and Blood Clots: What You Need to Know by Kathy Katella (4 August, 2021) Yale Medicine
So cases of VITT (vaccine-induced thrombotic thrombocytopenia) do exist, but they are rare: getting sick with Covid-19 carries higher risk than normal or when vaccinated, so on the whole, health professionals recommend you get the vaccine, even if it is Johnson & Johnson/Janssen or AstraZeneca.
==== It's the Mark of the Beast ====
Some Evangelical Christians have claimed that the COVID-19 vaccine is the Mark of the Beast or that it is the preparation for it.Elizabeth Dwoskin, On social media, vaccine misinformation mixes with extreme faith. Archived from The Washington Post, 16 February 2021. This is due to the fact that most of them are Republicans, with many of them having become antivaxxers due to QAnon.
One interpretation hinges on a conflation, or claimed derivation,https://www.patheos.com/blogs/progressivesecularhumanist/2020/10/christian-group-warns-new-covid-vaccine-is-mark-of-the-beast/ between the Ancient Greek terms χάραξ (charax) (meaning potentially "a pointed stake" and thus speculatively involving a needle)https://biblehub.com/greek/5482.htm and χάραγμα (charagma) meaning "a stamp, impress" or "sculpture; engraving, a stamp, sign".https://biblehub.com/greek/5480.htm They certainly aren't the same term and, though related, the latter does not derive from the former but rather from χᾰρᾰ́σσω (kharássō)."χαρακτήρ" at Wiktionary. The English word character derives from χᾰρᾰ́σσω (kharássō) too,"character" at Wiktionary. yet quite obviously has nothing to do with a needle, per se.You could have a character who is a needle or a vaccine. But we're getting off in the weeds here... Also, even if we suspended our justified disbelief and took it as fact that the Book of Revelation refers to a vaccine as the Mark of the Beast, there remains the question: for what reason should it be considered that this is talking about the COVID-19 vaccine in particular and not some other vaccine — or even any and all vaccines? The answers to these questions are certain to vary, and many will rely on further speculation and personal interpretation. Overall, this is rife with unsound leaps in logic, requiring a suspension of critical thinking to buy into.
== Situation in 2024 ==
=== Vaccine effectiveness ===
On 1 February 2024, the Centers for Disease Control and Prevention (CDC) estimated that the COVID-19 Vaccine Effectiveness against symptomatic SARS-CoV-2 infection has been 54% (95% CI = 46%–60%) in the period from September 2023 till January 2024 for immunocompetent adults recently vaccinated (median 52 days since vaccination) with a XBB.1.5–derived vaccine in the U.S. compared with those who didn't receive an updated vaccine.Early Estimates of Updated 2023–2024 (Monovalent XBB.1.5) COVID-19 Vaccine Effectiveness Against Symptomatic SARS-CoV-2 Infection Attributable to Co-Circulating Omicron Variants Among Immunocompetent Adults — Increasing Community Access to Testing Program, United States, September 2023–January 2024 (1 February 2024, www.cdc.com)
