Whilst many Americans have received the two-dose Covid-19 vaccines – which ‘promise’ full protection against the virus – Moderna has begun testing booster shots for fully vaccinated people.
One volunteer who took part in the trial – and was fully vaccinated with the Pfizer/BioNTech jab since January – said that he experienced “more severe side effects” after receiving the booster shot.
‘Virus expert’ Joseph Hyser (ironic) received an email asking if he would be interested in taking part in a trial for a third Moderna booster shot, to which he said yes.
The virologist at Baylor College of Medicine remarked “Ooooh I got boosted!” in excitement to his friends and family, who were bewildered as to why he chose to get a third jab.
The study Hyser took part in aimed to assess the effectiveness of the Moderna booster dose in people who received other Covid-19 mRNA vaccines and Johnson & Johnson’s one-dose vaccine, which received funding from the National Institutes of Health.
The trial is being conducted by Dr Robert Atmar from the Vaccine Research Center at Baylor.
Hyser said that he experienced “similar types of side effects” from Moderna’s and Pfizer’s vaccines, he said that the side effects were “a little bit more obvious with the Moderna.”
“I did, for Pfizer, have a little bit of chills, a little bit of muscle ache, but nothing prevented me from conducting my normal day-to-day activities.
“With the booster, it was a little bit more severe.”
He described that the day after he received the booster shot, he felt like he had done “a very rigorous gm workout,” with chills and arm soreness like he’d gotten a “hard punch in the shoulder.”
According to the virologist, he felt like himself again after he took some ibuprofen and had a day of rest.
Hyser said that he is expected to make around $600 (£434) in total over the course of this trial.
This is not Hyser’s first vaccine trial as he has participated in studies of smallpox shots, anthrax vaccines, and annual flu jabs.
Currently, in the UK, the government has announced that the most vulnerable could be offered a Covid-19 booster shot from September.
It’s expected that the planned rollout will take place alongside the annual flu vaccination programme and will be offered to those who are considered the most vulnerable.
