People who have been fully vaccinated for 3 months or more are allowed to receive the 3rd dose of vaccine.

On the morning of December 18, Mr. Tran Minh Tue - Deputy Director of the Department of Health said that up to now, nearly 2 million people in Nghe An province have been vaccinated against Covid-19. Of which, more than 1.5 million people have received the basic vaccination (reaching a rate of 46% compared to the total population and 77.4% compared to people aged 18 and over).

Not to mention, nearly 160,000 children aged 12-17 in Nghe An have also received the first injection. In addition, in Nghe An province, nearly 50,000 people have received additional injections.

Basic doseis the dose of vaccine injected according to the manufacturer's prescribed schedule. Vietnam is currently injecting mainly two-dose vaccines (usually called dose 1, dose 2), such as AstraZeneca, Pfizer, Moderna, Sinopharm vaccines..., each dose is injected 3-6 weeks apart depending on the type. Cuba's Abdala vaccine will be injected according to a 3-dose schedule...

Stillsupplementary doseis the dose injected at least 28 days after the last dose of the basic dose. This dose is for people who have received the full basic dose and have moderate and severe immunodeficiency such as people with organ transplants, cancer, HIV, are being treated with immunosuppressants or have been treated within 6 months...; people who have received the full basic dose of Sinopharm or Sputnik V vaccine.

According to the latest guidance from the Ministry of Health, they will be given a booster shot 28 days to 3 months after the last dose of the primary dose. The type of vaccine to be injected is the same as the primary dose or mRNA technology vaccine (Pfizer, Moderna). People who are indicated to receive a booster shot, after receiving the booster shot, are considered to have completed the primary dose.

Meanwhile,booster dose, also known as the booster dose, is intended for people 18 years of age and older who have received the basic dose or supplementary dose, ensuring coverage for all people with underlying diseases, people needing long-term care at medical facilities, people 50 years of age and older, people directly testing, caring for, and treating Covid-19 patients, and medical staff.

Regarding the type of vaccine, if the primary or supplementary injections are of the same type of vaccine, the booster injection will be of the same type or mRNA vaccine. If different types of vaccines have been previously injected, the booster injection will be of mRNA vaccine.

If the primary or supplementary dose is a Sinopharm vaccine, a booster dose of the same type or an mRNA vaccine or a viral vector vaccine (AstraZeneca vaccine) can be given.

The interval between 1 booster shot is at least 3 months after the last shot of the basic dose. Compared to the guidance issued by the Ministry of Health in early December, the time for additional injections has been shortened to 3 months, instead of 6 months as before. For those who have contracted Covid-19, the injection should be given immediately after recovery and completion of medical isolation according to regulations. Meanwhile, previously, people who had recovered from Covid-19 had to wait at least 6 months.

The Ministry of Health stated that the vaccines used for supplementary and booster injections are vaccines approved by the Ministry of Health. The doses of vaccines for supplementary and booster injections must comply with the manufacturer's instructions for use approved by the Ministry of Health.
