COVID-19 vaccine brand mix may help with delayed deliveries – experts


Now that the supply of coronavirus disease (COVID-19) vaccines in the Philippines is tight, some local experts are seeing the contribution of mixing brands of vaccines to the same person to fight the pandemic.

There is now concern that the second dose of the Sputnik V vaccine will not be given immediately to those who received the first dose within the allotted 21 days. As a result, the delivery of an additional 50,000 doses of the drug to the Philippines has now been delayed.

“Isa sa mga challenges natin ngayon is ‘sourcing young…’ Yung brand mix can help,” Dr Isagani Padolina, member of the DOST Vaccine Expert Group (VEP), said on Friday.

“So if you have the option to replace that second dose with another brand… It will still work. So we have studies underway for these.

The Department of Health first said in May that it was already drafting rules for mixing brands of vaccines.

Under Secretary of Health Maria Rosario Vergeire said the brand mix of vaccines had already been found on a theoretical basis. One of the countries implementing the “brand mix” is the United Kingdom. However, the government is still studying it.

The supply of CoronaVac vaccines by drug maker Sinovac in the Philippines was also recently halted after failing to submit the required documents. However, it was also distributed after such a deficiency.

In presidential spokesman Harry Roque’s latest report on Thursday, up to 16.2 million doses of COVID-19 vaccines have arrived in the Philippines, including 2 million doses of Sinovac which just arrived in the country yesterday.

According to Dr Rontgene Solante, who is also a member of the VEP, there is no immediate concern, even if the second dose of the COVID-19 vaccine is injected a bit late.

Like the Pfizer vaccine, Solante said that the Russian Sputnik V vaccine’s effectiveness rate is also high. However, he said it would be dangerous if the difference between the first and second dose was six months to a year.
