Coronavirus (Covid-19)

Top virologist says vaccine boosters will be needed to maintain Covid protection

A prominent virologist from Bangkok’s Chulalongkorn University says it’s likely that people vaccinated against Covid-19 will still require boosters in order to remain protected. Yong Poovorawan shared his views in a Facebook post yesterday, after a study of recovered patients showed that their immunity to the virus started to drop between 3 and 6 months after infection.

“It is highly likely that a third dose of the Covid-19 vaccine will be needed and it is possible that people will need to get vaccinated against the coronavirus periodically.”

Yong says the incubation period of a virus will determine a vaccine’s effectiveness, with jabs usually performing better against illnesses with longer incubation periods, such as chicken pox and measles. However, Covid-19 has a shorter incubation period of between 2 and 7 days, and this means booster shots are likely to be needed.

According to a Bangkok Post report, the virologist has also warned that people who’ve been vaccinated, or those who’ve already had the virus, can be re-infected, although symptoms in a second infection are usually not as severe. Yong insists the national vaccine rollout is essential, saying the jabs will prevent hospitalisation and death.

The Centre for Covid-19 Situation Administration says 618,583 people were vaccinated between February 28 and April 18. On Sunday, 9,219 received their first vaccine dose, while 843 received the second. The Thai government has been criticised in many quarters for the slow pace of the vaccine rollout and its vaccine procurement strategy, which saw orders limited to just 2 manufacturers. PM Prayut Chan-o-cha recently stated that the government would try to obtain more vaccines from Russia and the US, but there has been no indication of when these might arrive.

    Top Virologist hey ? I can name many top immunisation doctors who say Herd immuity is the most natural way to move life ahead but Govt will not listen to alternative professional opinions.The good thing is some parts of the world are waking up to this which is a good sign.

    “Top Virologist hey ?”

    Yes, @George.

    Not just in Thailand and Asia but his research articles (he was a research fellow at King’s College) make him one of the most cited in the world.

    Unlike the assorted YouTube nutters proposing “natural herd immunity”, which no serious respected virologists and epidemiologists support (as distinct from vaccinated herd immunity), “yes”, he is a genuine “top virologist”.

    I watched a vaccine expert discuss that vaccinations in the middle of a pandemic is really dangerous as this is how the virus will mutate beyond the vaccine.

    Only the stupid will get the vaccine… and the boosters. This might mean I will be shunned from freedom, but I’m going to compromise my health with a vaccine.

    What I still don’t understand is, why can’t only the people who are afraid of the virus, get the vaccine. They’re now protected. I’ve done my research and I don’t see covid as being dangerous statistically to my gender and age group. We also have many treatments available now to treat covid patients with severe symptoms… why are we still afraid of it?
