As the world waits with bated breath for an effective and safe COVID-19 vaccine, several pharmaceuticals like Moderna and Pfizer, are currently testing out vaccines on thousands of volunteers as part of double-blind phase three trials.
After one such trial, five human trial participants of Moderna and Pfizer, said they experienced exhaustion, fever and headaches for a whole day after being injected.
The participants of the coronavirus vaccine trials - three in Moderna's study and two in Pfizer's late-stage trials - said high fever, body aches, bad headaches and exhaustion are just some of the symptoms they experienced after receiving shots.??
According to CNBC, a Moderna vaccine trial participant suffered night chills with a fever, after the booster shot.
Another Pfizer vaccine candidate volunteer said that he wokeup with chills that were so bad that he cracked a tooth.
After about 12 hours, he felt normal. Two other participantsin the Moderna also experienced similar symptoms after receiving thecoronavirus vaccine doses.
Another participant, in her 50s, in Moderna study of the coronavirus vaccine trial, said she didn't experience a fever but suffereda bad migraine. She said while the first coronavirus vaccine candidate dose was"no big deal", the second one will definitely put people down for aday.
¡°If this proves to work, people are going to have to toughen up,¡± she said. ¡°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.¡±
Florian Krammer, a virologist at the Icahn School ofMedicine at Mount Sinai in New York, tweeted that the self-reported sideeffects were ¡°unpleasant but not dangerous¡± for Moderna¡¯s mRNA-based vaccinecandidate.
Experts now have the task of educating those who may seethese side effects as a reason to not get the vaccine at all, as STAT reportedin July.
