Malaysian medical experts: No evidence to show mixing Covid-19 vaccines harmful, booster shots still safest way to protect yourself

KUALA LUMPUR, Jan 4 — Two years into the Covid-19 pandemic and with 78 per cent of the entire inhabitants absolutely vaccinated, there was still hesitancy about booster jabs when it was first rolled out final October.

A excessive variety of individuals with appointments merely didn’t flip up.

Many had been afraid of mixing vaccines though medical consultants say there may be completely no cause for the distrust, particularly for individuals who have been administered Sinovac jabs.

“Repeated messages ought to be despatched addressing doubts and it’s value noting the opposed reactions will not be larger when vaccines are combined.

“The World Health Organisation (WHO) regional director Hans Kluge stated there might be half one million deaths in Europe by the primary quarter of this yr if they didn’t return to the way they had been by sporting masks and growing vaccine uptake,” he added.

Booster shots had been administered nationwide beginning October 13 for absolutely vaccinated people in addition to for senior residents aged 60 and above and frontliners who’ve accomplished vaccination after six months.

He was requested if recipients of the Sinovac vaccine who acquired the Pfizer booster shot in Malaysia might require a fourth dose sooner or later, to which he stated the matter was still being studied.

Khairy stated the Health Ministry’s technical staff can be proposing suggestions to the Covid-19 Immunization Task Force (CITF) after finishing a couple of research of its personal, including that it was still too early to draw any particular conclusions.

A report cited by eNM yesterday stated the Sinovac two-dose regime, together with the Pfizer booster shot, produced an antibody response comparable to a two-dose mRNA vaccine like Pfizer and Moderna.

Public Health Medicine Specialist and Professor of Epidemiology on the Department of Social and Preventive Medicine, Faculty of Medicine, University of Malaya Dr Sanjay Rampal agreed with Dr Helmy that the pushback in opposition to heterologous shots is unsubstantiated.

“Those who’ve gotten two earlier Sinovac shots ought to be inspired to get a Pfizer booster. However, there may be resistance from sure components of the group that still solely choose Sinovac, a possible results of both trusting the reported results of Sinovac or distrusting Pfizer.

“Grassroots leaders have to be engaged to view the evidence objectively and promote higher vaccines. Quite a lot of Sinovac vaccines have additionally been bought. A moratorium on additional purchases could also be indicated pending extra full evidence-based experiences,” he stated.

She stated current evidence still means that booster shots assist protect in opposition to the Omicron variant.

“To date, there was no evidence of significant opposed occasions from populations who acquired heterologous (combined) vaccines from different components of the world.

“So, this could function a reassurance that it’s okay to obtain Sino-Sino-Pfizer,” she stated.

However, the preliminary booster hesitancy amongst older Malaysians appears to have been overtaken by youthful Malaysians keen for his or her booster shots.

Over the weekend, lengthy queues fashioned at a number of malls round Klang Valley the place booster shots had been being given.

Paradigm Mall in Kelana Jaya, iHeal Medical Centre in Kuala Lumpur and Subang Parade PPV had been among the many areas the place massive crowds had gathered for walk-in booster shots.

This was a results of Putrajaya shortening the interval interval for all Covid-19 vaccine recipients to three months.

Coupled with the latest floods in Kelantan, Pahang, Johor, Negri Sembilan, Kuala Lumpur and Selangor which brought on some clusters to emerge on the momentary aid centres, Malaysians are selecting to protect themselves.

As the nation enters the endemic part and worldwide borders are set to reopen to international travellers, the necessity to be immunised is even higher as extra virulent strains of the coronavirus seem.

“In the top, every thing we do is to mitigate danger. Wearing masks, avoiding crowded areas and getting vaccinated will not be ensures to forestall contracting the virus,” stated Dr Helmy.

“What we can’t argue with is the truth that the pandemic is lethal to those that can’t mount an acceptable immune response.”
