# COVID-19 vaccination in Vietnam

The COVID-19 vaccination in Vietnam is an ongoing immunization campaign against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in response to the ongoing pandemic in the country. Following the approval of the Oxford–AstraZeneca COVID-19 vaccine on 30 January 2021, vaccinations commenced on 8 March 2021, and will continue throughout the year with the goal of vaccinating 80% of the population by June 2022. The Sputnik V was later approved for use on 23 March 2021. The Sinopharm BIBP vaccine was approved for emergency use on 4 June 2021, while Pfizer–BioNTech COVID-19 vaccine, Moderna COVID-19 vaccine and Janssen COVID-19 vaccine were approved on 12 June 2021, 29 June 2021, and 15 July 2021, respectively. Vietnam approved Abdala vaccine from Center for Genetic Engineering and Biotechnology on 18 September 2021, and Covaxin from Bharat Biotech on 10 November 2021.
This is the country's largest-ever immunization campaign, aiming to administer over 150 million doses. As of 6 April 2022, Vietnam has administered 207,235,119 vaccine doses across the country.

## History

In August 2020, the Vietnamese government announced that they had signed up for 50 to 150 million doses of Sputnik V vaccine from Russia. The Russians will also donate a number of machines, biological products and equipment to Vietnam for COVID-19 prevention, including their vaccine. In the meantime, Vietnamese researchers will still continue developing the country's own vaccine. In early June, Minister of Health Nguyen Thanh Long confirmed that Russia had agreed to provide Vietnam with 20 million doses of Sputnik V in 2021. Vabiotech will also start packaging Sputnik V vaccine in Vietnam from July, with a monthly capacity of five million doses. On 21 July 2021, it was announced that a batch of Sputnik V had been produced for the first time in Vietnam by Vabiotech. Before that, on 12 July 2021, the Government allowed T&T Group to negotiate with the Direct Investment Fund of the Russian Federation (RDIF) for 40 million additional doses of Sputnik V vaccine, using its own fund; not from the government budget or Vietnam's vaccine fund. On August 4, 2021, Vimedimex signed an import contract with an UAE-based company called Royal Strategics Partners, for 10 million doses of COVID-19 Janssen vaccine; 5 million doses of COVID-19 vaccine Pfizer; 10 million doses of COVID-19 vaccine Sputnik V. Currently, the parties are completing legal documents to submit to the Ministry of Health for an import license.
In February 2021, the Ministry of Health suggested the government to approve COVID-19 vaccines from AstraZeneca, Gamaleya, and Moderna for domestic inoculation to prevent and control the ongoing pandemic in the country. National Deployment and Vaccination plan (NDVP) was signed off by Deputy Minister of Health on 9 February 2021. Vietnam will receive the feedback of the plan from NDVP review committee as one of the required steps to receive COVID-19 vaccines through COVAX Facility – a global mechanism for developing, manufacturing, supplying and procuring COVID-19 vaccines for all country, especially for low and middle-income economies. Through COVAX, it is confirmed that Vietnam will receive 38.9 million doses of COVID vaccine in 2021. The first batch of vaccines sourced via Covax mechanism, containing 811,200 doses, arrived in Hanoi's Noi Bai International Airport on 1 April 2021. On 6 July, it was confirmed that the United States would send Vietnam two million doses of Moderna COVID-19 vaccine via Covax mechanism. 10 days later, on 16 July, the US embassy in Hanoi informed the Ministry of Health that the country will support Vietnam with 3 million additional doses of Moderna vaccine.

In July, The Ministry of Health also allowed a company in Ho Chi Minh City, Sapharco, to import 5 million doses of the Sinopharm BIBP vaccine. This is the second company in Vietnam allowed to import the COVID-19 vaccine, after VNVC. The Sinopharm BIBP vaccine will be administered to Chinese nationals in Vietnam, those wishing to go to, study or work in China and those living in border areas with China. On late July and early August 2021, Ho Chi Minh City received 2 million of the 5 million doses of the vero cell Sinopharm BIBP vaccine purchased by Sapharco.

* Even when the Chinese announced it would provide priority access to CoronaVac and the Sinopharm BIBP vaccine, Vietnam is the last ASEAN nation to publicly state if it will use this due to anti-China sentiment among the public. It is also one of the last to approve a Chinese vaccine.
* For locally produced COVID-19 vaccines, the MOH expects to have the first batch ready for use at the end of the third quarter of 2021. These vaccines can be put into the country's vaccination campaign in 2022 to ensure supply source and health security, overcome the difficulties when purchasing foreign vaccines. The two locally produced vaccines, Nanocovax and COVIVAC, were put on trial on January to March 2021, respectively. On 21 July 2021, the first test batch of Russia's Sputnik V vaccine has been produced in Vietnam, according to Russia's sovereign wealth fund RDIF and Vietnamese pharmaceutical company Vabiotech. The first validation samples taken from the batch were shipped to Gamaleya Center in Russia for quality control checks. On 24 September, the vaccine began to be mass-produced when it was determined that it met the quality standards.

* A spokesman from the Covivac vaccine development team stated on November 30, 2021, that they are currently unable to locate a location with several thousand people who have not been inoculated against COVID-19 and are eligible to participate in clinical trials. As a result, the development team opted to halt the phase three experiment indefinitely.

## Rollout plan

VNVC – the company in charge of importing and storing vaccines in Vietnam, announced that it is ready to deploy staff and facilities that can store up to 170 million doses of vaccines. The facilities include 49 provincial vaccine warehouses, 2 cold-condition warehouses, and 3 deep-freeze warehouses designed for storing vaccines at temperatures ranging from -40 to -86°C. In February 2021, VNVC's service capacity was reported to reach up to 100,000 customers per day, with the capability to scale up to accommodate the distribution of up to 4 million doses of COVID-19 vaccines per month.
According to Deputy Minister of Health Tran Van Thuan, for the majority of the population to be protected, Vietnam needs to diversify its vaccine supply. This diversification includes using locally manufactured vaccines and the maximizing resources from businesses and local government budgets, in addition to the national government's budget, to support the vaccination program. The budget for vaccinating 20% of the population is estimated at 6.739 trillion VND ($293.67 million USD), with more than 90% of this cost covered by the COVAX Facility. The Vietnamese government will contribute 24 billion VND, complemented by municipal and provincial governments and private sources.
On 24 June 2021, the Ministry of Health established a Steering Committee for the nationwide COVID-19 vaccination campaign. The committee consists of five subcommittees:
* Subcommittee on Receiving, Transporting, and Preserving Vaccines
* Subcommittee on Immunization
* Subcommittee on Safety of Vaccination
* Subcommittee on Quality Supervision of Vaccines
* Subcommittee on Information Technology Application in Vaccination Management and Communication
along with a permanent office for the Steering Committee. The National Steering Committee for the COVID-19 vaccination campaign is headed by the Minister of Health. The command center of the vaccination campaign is located at the Ministry of Defence, led by a Deputy Chief of the General Staff of the People's Army. It is expected that the campaign will utilize eight vaccine storage warehouses, with one warehouse in each military district and another at the High Command of Capital Hanoi. Upon arrival at the airport, vaccines will be immediately transferred to the military warehouse, from where they will be transported by military vehicles to 19,000 vaccination points nationwide.
