The second dose of most vaccines usually has stronger side effects than the first dose, according to Food and Drug Administration (FDA) director general Eric Domingo on Tuesday.

“For most of the vaccines, the second dose really has more adverse effects, more side effects that patients feel,” he said during an interview with ANC.

Domingo made the statement after reports surfaced that people might experience fever and vomiting after getting the second dose of Moderna’s coronavirus disease 2019 (Covid-19) vaccine.

He explained that the first shot introduces the body to the vaccine so it can start creating anti-bodies in the first few weeks after the vaccination. 

“So pagdating ng second dose mas malakas ‘yung immunologic reaction,” he said.

Meanwhile, Department of Health (DOH) Secretary Francisco Duque III has advised senators to create a law for the indemnification of Filipinos who might experience adverse effects of Covid-19 vaccines

He asked lawmakers to include this in the third emergency law which aimed to address the impact of the Covid-19 pandemic in the country. Both proposals for the third emergency law have been already filed in both houses of Congress.

“Hindi naman po kasi pwede ipagkaila na hindi mangyayari o walang walang mangyayaring adverse events,” Duque had said.

“Hopefully wala, pero alam naman po natin kahit na papano, itong mga bakuna ay talagang may kaakibat na adverse events,” he added.

However, Senator Risa Hontiveros mentioned that there’s no decision yet if Congress would allow the third emergency law. Ronald dela Cruz
