Why does my arm hurt after the first Pfizer shot?

Do COVID-19 mRNA vaccines have long-term effects?

The Pfizer and Moderna vaccines were created using messenger RNA (or mRNA) technology, which has been used for about 10 years in cancer treatment, with no long-term effects detected. And even before that, scientists had been working with mRNA technology for years. 3. mRNA technology does not alter your DNA.

What are the most common side effects of the COVID-19 vaccine?

Fatigue and pain at the injection site were the most commonly reported side effects—and overall, most symptoms were mild and temporary. As with the two-dose primary series, serious side effects are rare, but may occur.
