Dr Adeeba Kamarulzaman is shocked that only 4% of Africa have been vaccinated against Covid-19 while other countries, including Malaysia, are planning booster shots.
Even with waning immunity, this doesn’t necessarily mean that the body’s capacity to respond to subsequent exposure of the Covid-19 virus is gone because we have immunologic memory of past infection or vaccines, say immunologists.
Health DG’s statement did not specify if the National Pharmaceutical Regulatory Agency gave regulatory approval for heterologous vaccination with a Pfizer booster dose.
Khairy Jamaluddin also emphasises personal responsibility when travelling interstate, as it’s impossible to mount roadblocks to check for unvaccinated travellers.
Khairy Jamaluddin says JKJAV’s technical sub-committee has recommended using a different vaccine for a third dose in the Covid-19 booster vaccination programme.
Immunologists and virologists say there is no strong scientific data in Malaysia yet that shows waning immunity from Covid-19 vaccines that still protect against severe disease and death.
Muhyiddin Yassin says this is a result of the government’s previous decision to order more than enough vaccines for the needs of the Malaysian population.
Khairy Jamaluddin says the third shot is for people who don’t gain sufficient immune response from two doses of the Covid-19 vaccine, whereas boosters are to curb waning immunity in other individuals who responded well to double vaccination.
