page_title: Q&A on coronaviruses (COVID-19)
section_headers: What can I do to protect myself and prevent the spread of disease?
section_content: Stay aware of the latest information on the COVID-19 outbreak, available on
the WHO website and through your national and local public health authority.
Most countries around the world have seen cases of COVID-19 and many are
experiencing outbreaks. Authorities in China and some other countries have
succeeded in slowing their outbreaks. However, the situation is unpredictable
so check regularly for the latest news.
You can reduce your chances of being infected or spreading COVID-19 by taking
some simple precautions:

Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water. Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
Maintain at least 1 metre distance between yourself and others. Why? When someone coughs, sneezes, or speaks they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person has the disease. 
Avoid going to crowded places. Why? Where people come together in crowds, you are more likely to come into close contact with someone that has COVID-19 and it is more difficult to maintain physical distance of 1 metre. 
Avoid touching eyes, nose and mouth. Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and infect you. 
Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately and wash your hands. Why? Droplets spread virus. By following good respiratory hygiene, you protect the people around you from viruses such as cold, flu and COVID-19. 
Stay home and self-isolate even with minor symptoms such as cough, headache, mild fever, until you recover. Have someone bring you supplies. If you need to leave your house, wear a mask to avoid infecting others. Why? Avoiding contact with others will protect them from possible COVID-19 and other viruses. 
If you have a fever, cough and difficulty breathing, seek medical attention, but call by telephone in advance if possible and follow the directions of your local health authority. Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections. 
Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities. Why? Local and national authorities are best placed to advise on what people in your area should be doing to protect themselves.


Reviewer feedback on this answer:
Information is relating to all of the steps an individual needs to take to protect themselves from COVID-19 but does mention the BCG vaccine at all.
This answer is irrelevant to the question. The question is asking about BCG vaccines and its protection against Covid-19 and this answer is providing information on how people can protect themselves against Covid-19 and ways to lower their chances of being infected or spreading the virus.

Answer passage (source: WHO):
page_title: Q&A: Tuberculosis and COVID-19
section_headers: Does the BCG vaccine protect people from COVID-19?
section_content: There is no evidence at this point that the Bacille Calmette-Guérin vaccine
(BCG) protects people against infection with COVID-19 virus. Clinical trials
addressing this question are underway, and WHO will evaluate the evidence when
it is available. In the absence of evidence, WHO does not recommend BCG
vaccination for the prevention of COVID-19. WHO continues to recommend
reserving BCG for neonatal vaccination in settings with a high risk of
tuberculosis.

Reviewer feedback on this answer:
Answer is honest about the fact that there is no evidence that the BCG vaccine will help against COVID-19 as well as making sure that people don't try to get the vaccine in the hope that it might.
This answers the question directly. This answer provides information on BCG vaccines and whether or not it can protect a person from contracting Covid-19.

Answer passage (source: WHO):
page_title: Q&A: HIV, antiretrovirals and COVID-19
section_headers: Can antiretrovirals be used to prevent COVID-19 infection?
section_content: Two studies have reported the use of LPV/r as post-exposure prophylaxis for
SARS-CoV and MERS-CoV. One of these studies suggested that the occurrence of
MERS-CoV infection was lower among health workers receiving LPV/r compared to
those who did not receive any drugs; the other study found no cases of SARS-
CoV infection among 19 people living with HIV hospitalized in the same ward of
SARS patients, of whom 11 were on antiretroviral therapy. Again, the certainty
of the evidence is very low due to small sample size, variability in drugs
provided, and uncertainty regarding intensity of exposure.  

Reviewer feedback on this answer:
Answer does not mention COVID-19 or BCG at all and merely revers to people living with HIV and those with SARS-CoV and MERS-CoV.
This answer is irrelevant to the question. This answer provides information and study findings on the use of LPV/r as post-exposure prophylaxis for SARS and MERS coronavirus and also SARS-CoV infection case among HIV patients who are hospitalized together with SARS patients. However, the question is asking about BCG vaccination and its possible protection against the Covid-19.
