Some participants for leading COVID-19 vaccine trials have reported experiencing grueling side effects after receiving the shot — such as high fever, body aches, headaches and exhaustion.
Five participants — three in Moderna’s study and two in Pfizer’s late-stage trials — said the uncomfortable side effects usually went away within a day, but some were surprised by how severe they were, CNBC reported.
“If this proves to work, people are going to have to toughen up,” one of the Moderna participants, a North Carolina woman in her 50s who declined to be identified, told the outlet.
“The first dose is no big deal. And then the second dose will definitely put you down for the day for sure. … You will need to take a day off after the second dose.”
She said she didn’t experience a fever but had a bad migraine that left her exhausted and struggling to focus, the outlet reported. But the next day, she woke up feeling better after taking Excedrin.
While she was uncomfortable, the side effects outweigh the risks of becoming infected with the virus, she said.
