4.Scientists’ views on the third dose
Scientists have been divided on this matter. An expert view of scientific evidence has concluded that Covid-19 vaccine booster shots are not needed for the general public. They say that unnecessary boosting can cause unnecessary adverse reactions, such as myocarditis–rare heart inflammation. However, scientists have acknowledged that booster shots might eventually be needed for the general population if vaccine-induced immunity wanes even further or a new variant emerges that can evade the protection of the shots.

Whereas, Pfizer was only 60% effective at preventing hospitalizations among adults of similar age groups. And, Jhonson & Johnson was 60% effective.
But, FDA vaccine official Doran Fink told the panel that the agency is “working as rapidly as possible” to review Moderna’s booster submission.
Some experts have questioned whether people who have received two doses of Moderna or a single dose of J&J vaccine should receive the Pfizer booster, or whether they should wait to match with a supplemental dose of the shot they first received.
7. WHO’s opinion of Pfizer booster shot
The World Health Organization Director-General Tedros Adhanom Ghebreyesus said that booster shots should wait until immunisations are more widespread globally. The WHo chief has argued that uneven vaccine distribution will be the world’s biggest obstacle to ending the pandemic and recovering
