NOVEMBER 27 ― The Pfizer vaccine is touted to have a staggering 95 per cent efficacy. But according to the, recent unpublished data from Israel shows the Pfizer vaccine was only 40 per cent effective at reducing the risk of symptomatic Covid-19.
To fathom this dichotomy of 95 per cent efficacy versus 40 per cent effectiveness or 68 per cent effectiveness shown by the Pfizer vaccine, there is a need to understand the difference between efficacy and effectiveness. In the Pfizer study, the company tested about 44,000 people for symptomatic Covid-19 and only 170 developed the disease with at least one symptom. And of those, just eight had been vaccinated while 162 got a placebo. This is what added up to that 95 per cent efficacy rate.
And what makes it all the more complicated and unfathomable is the virus itself is still evolving via mutation in which the delta variant has become dominant in many countries and more transmissible than earlier strains of the virus. What the programme is trying to achieve is to ensure immunity is kept high enough, hence increasing the chances the vaccine would prevent severe illness that could then lead to hospitalisation and deaths.
It has since been proven by data worldwide that among Covid deaths, the majority comprises those who were not vaccinated and those with only one dose of vaccination, hence the endemic policy of relaxing restrictions only for those who were fully vaccinated. He further explained the faster waning period is the reason why the interval for Sinovac booster shots is three months, compared with six months for Pfizer and AstraZeneca.
Agreed 100% 👍👍👍👍👍 === [Experts also recommend preventive measures like - mask wearing and - social distancing to keep the virus from spreading and mutating further]
This is stupid, how many booster required if new variants keep surfacing?
They only have 1 plan, vaccine booster only. They didn't improve the work to keep the virus shut out, please learn a bit from China how to govern the pandemic situation, don't let race or country pride blind your eyes.
Khairykj Keep talking and no real action....really piss off. Other countries are providing vaccines to AZ and Sinovac sooner as they know antibody is much lower than MNRA...our minister keeps talking and no real improvement
