Adults have sharply higher risks of being diagnosed with heart, skin, and psychiatric conditions for at least 90 days after they receive Covid jabs, a peer-reviewed study of almost 300,000 people in California has shown.
The researchers examined new diagnoses given to the same people before and after they were vaccinated to see whether the shots changed the risk of new health problems.
They found that people were about 21 percent more likely to receive a new diagnosis in the three months after a shot, compared to the three months before. With almost 240 million American adults jabbed, the rise translates into millions of extra new medical problems found in the months after vaccination, and tens of millions worldwide.
Serious conditions such as hypertension were about 25 percent more likely to be diagnosed in the three months following a shot than the three months before, the researchers found.
