The US of America, as an illustration, solely has two mRNA varieties – Pfizer and Moderna – and one viral vector, Janssen.
“With the rise of variants, an excessive amount of emphasis on spike protein will increase the chance of antigenic escape. Regardless of the Western bias towards Chinese language manufacturers, the inactivated vaccines (of Sinovac and Sinopharm) even have extra antigen epitopes except for spike protein. This makes them extra prone to be resilient to variant mutations,” Salvana mentioned.
The Philippines was additionally one of many earliest nations to adapt boosters at three-month intervals.
Earlier than the Omicron variant prompted a spike in circumstances, Salvana famous the TAG and all specialists group reviewed information and adopted the advice for booster pictures.
“As well as, due to our vaccine model variety, many individuals ended up with heterologous boosters which can be simpler towards variants than homologous ones,” he mentioned.
The spike in circumstances in January was pushed by the BA.2 sub-variant of Omicron, not like the surges in different nations which had the BA.1 sub-variant.
“We noticed principally BA.1 amongst quarantined vacationers, which suggests they did not make it to the neighborhood. Sadly, somebody with BA.2 made it by way of.

He added that the federal government’s preemptive lockdowns delayed the spike in circumstances attributable to the Delta variant “so the hybrid immunity from breakthroughs from August 2021 was nonetheless comparatively contemporary”.
“We anticipate BA.2 hybrid immunity (BA.2.3 to be actual since BA.2 within the Philippines has been designated its personal sublineage) to guard towards different BA.2 sublineages, together with BA.2.2 which is wreaking havoc in Hong Kong,” he mentioned.
From March 7 to 13, there have been solely 4,131 new Covid-19 infections whereas intensive care unit mattress utilization is at a mere 19.6 p.c as of March 14.
A complete of 64.5 million or 71.71 p.c of goal are already full vaccinated
Salvana cautioned {that a} spike is all the time doable so complacency should be averted.
