Prof Cook: Boosters reduce the risk of infection, making up for the waning immunity, but it is unclear how long this lasts

Q: Does this mean booster shots are needed every few months if more variants of the virus surface?​

A: Boosters reduce the risk of infection, making up for the waning immunity, but it is unclear how long this lasts, said Associate Professor Alex Cook, vice-dean of research at the National University of Singapore's Saw Swee Hock School of Public Health.

"It could be that boosters are long lasting and the third dose is all we need for lasting protection against infection, but it could also be that the immunity wanes again just like with the first two shots, which is compromised by the emergence of new variants," Prof Cook said.

"If the latter is true, after we get past the pandemic phase, the health system may be able to cope even if only the most vulnerable take occasional booster doses, just as it does with influenza."

we need more data on this.

His brain must be cooked to make such half baked statements.

Prof Cook should read the news on 2x local booster break-through infections with omicron...

New research finds that COVID-19 vaccine-resistant mutations strongly correlate with vaccination rates.
"By tracking the evolutionary trajectories of vax-resistant mutations in more than 2.2 million SARS-CoV-2 genomes, we reveal that the occurrence & frequency of vax-resistant mutations correlate strongly with the vaccination rates in Europe and America."

Obviously Prof Cook is not updated and not a member of edmw. Pfizer and Moderna already said 3rd shot not enufg, need to keep shooting. 2nd shot wane from 5th mth, booster will be shorter than 5mth.

Only 65-70% eligible took up boosters.
Chewren < 12 notch even taken 1st shot.
Probably won't make it in time to counter community spread.

I think better to make a full booster and a 1/2 booster.
Let ppl choose
2.5-3 mths to take a 1/2 booster.
5-6 mths to take the full booster.

Recent booster trial hab shown that a 1/2 booster ish ~85% strength in boosting immunity in comparison to the full booster at 3 month point.
In times of crisis, allow a choice of the 1/2 booster within a shorter time frame allow for a more nimble response to newer variants.
In more peaceful times, a full booster every 5-6 mths or even longer ish a lot better.

The only issues ish logistics and statistics.
Having some injection syringe at 1/2 or full dose rate might be confusing to the administrators, and stats for booster dose would probably need to accept those taking a 1/2 dose as 1/2 a person and also cost of the use of each syringe and needles and personnel involved.

whatever happened to there's no evidence... blah blah blah?

i thought scientists need to show proof in order to make claims?
