Why Vaccine Safety Numbers Are Still Fuzzy

“I would often say that the risk of a blood clot forming with birth control pills is similar to a really serious reaction to penicillin,” said an obstetrician-gynecologist, Dr. Regan Macdonald-Mosley said. And CEO of Power of Decide, a group dedicated to reducing unintended pregnancy. She often discusses blood clotting risk with her patients, telling them about increased risk and the overall magnitude of that risk. Most patients said, choose their form of birth control based on other births.

Penicillin, a widely used antibiotic, causes severe allergic reactions. Between one and five patients for every 10,000 Who takes

For vaccines, however, The threshold for safety is usually higher than other types of drugs. As noted by many researchers, Kovid-19 puts people at risk of severe blood clots, that too – much higher than any perceived estimate of the vaccine effect. But everyone who fails to get vaccinated is not going to get sick.

“The disease, which you get by chance, and the vaccine you get by choice, and that makes it difficult,” Dr. Said Steven Black, a professor of paediatrics at Cincinnati Children’s Hospital, who studies vaccine safety.

For other vaccines, the risk of serious adverse events is much lower than birth control pills or penicillin – they typically occur in less than 1 in 100,000 who receive a given vaccine. This rate is “obviously too low, too low for a drug to be tolerated”, said Dr. Kaiser Permanente Vaccine Study Center Director Dr. Said Nicola Klein, who is involved in the vaccine safety datalink study.

Most other vaccines protect against diseases that are rare. In contrast, Kovid-19 is widespread throughout America and many parts of the world. Given the severity of the disease and the ease of its spread, the value of vaccination may be higher than at a time when such trade is commonly considered.
