Side effects from COVID-19 vaccines range from nausea and flu-like symptoms to nothing at all — but your reaction says nothing about how you would have fared against the virus, experts said in a report Friday.
“I don’t think that there’s any relationship between your reaction to the vaccine and what would have happened to you had you gotten infected with the virus,” Dr. William Schaffner, an infectious diseases expert from Vanderbilt University, told the CBS affiliate WFMY.
But regardless of the severity of post-vaccination symptoms — which this week included nausea and dizziness for 11 people at a shuttered Colorado Johnson & Johnson jab site — the shots are equally effective for everyone, experts said.
“People will say, ‘Well if I didn’t get a reaction, does that mean the vaccine didn’t work?’ and the answer is, no,” Dr. William Moss, a vaccines expert from Johns Hopkins University, told the outlet.
He added, “My short answer is [there are] no implications for protective efficacy…No implications for how your body would respond if you got infected with the actual SARS-CoV-2.”
On Wednesday, around a dozen people reportedly suffered adverse reactions to the Johnson & Johnson vaccine at Dick’s Sporting Goods Park in Commerce City, prompting officials to shutter the site.
The Colorado Department of Public Health and Environment later stressed that the side effects experienced were “consistent with what can be expected” with the single-dose shot.
As of Friday, more than 112 million people had received at least one dose of the COVID-19 vaccine in the US
