Dr. Manoon has a question: the last injection is 4 months old, is it okay to vaccinate the new model?

Today (20 Dec ’22), MD Manoon Leechawengwong, respiratory system specialist Vichaiut Hospital He posted a message on his personal Facebook page about the new vaccine, stating that I had 5 injections of the vaccine, 2 injections of Sinovac, 1 injection of AstraZeneca and 2 injections of Moderna, recently infected. There are very few symptoms like a common cold. just runny nose

In my family, many people are infected with COVID. But no one was seriously ill. To the point of having to go to bed in the hospital. Because everyone received a full dose of vaccine and a booster. demonstrates the effectiveness of the vaccine Unlike people in the 608 risk group who have never injected themselves or have only given 1 injection, most of them are seriously ill. Some had respiratory failure and died.

Someone asked me if the last vaccination was more than 4 months before it was time for the booster. Do I have to go get the new vaccine? Will fly to pick up in countries where they have new vaccines instead of the old vaccination in Thailand I commented that You don’t need to fly to get the new vaccine. Please inject the current version in Thailand first.

The new vaccine consists of two strains: the original Wuhan strain and the BA.5 strain. The global BA.5 virus is now being replaced by new sub-strains such as BQ.1 and XBB, which can evade it. The new vaccine can’t keep up with the COVID virus. The new vaccination can still get infected. But whether vaccinating older models or newer vaccines can still reduce serious illness and deaths. In the future, there will be vaccines to prevent 3-4 strains of COVID like the flu shot.

Therefore, there is no need to fly abroad now to get the new vaccine. People who have received fewer than 4 doses of vaccination are encouraged to inject the current vaccine first in Thailand.
