Herd Immunity Through Vaccination

Covid-19 is still very much active all around the world.

WHO support achieving 'herd immunity' through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths. 

Needless to say, the Malaysian government support the WHO position.




Let me say it again. Covid-19 vaccines are NOT 100% effective. 

Even so, the New England Journal of Medicine published a report on April 06 about Moderna's vaccine, saying it should offer protection from Covid-19 for at least six months. The study was based on follow-ups with dozens of people who were vaccinated during Moderna's trial phase. 

(I'm putting words like 'should' and 'dozens' in italics because they don't significantly mean anything actually).

Still, in a statement a week earlier, Pfizer mirrored the same time frame, saying their vaccine would also be effective for at least six months. 

Emerging variants, however, are where things get tricky, raising concerns over whether the vaccine has a fighting chance against variations of the virus that could show up in the future. 

Dr. Davey Smith (left), the chief of infectious diseases and global public health at UC San Diego, countered: “We just don't have enough time to figure out how long these immune responses last for these vaccines”.

Anyway, these are the facts as we know them today. 

Now you know why there are those of us who are hesitant and/or reluctant to take the vaccine.
