The Johnson & Johnson vaccine has started to make its way into the arms of Americans, and now patients have started to talk about the side effects.

What are the side effects of the J&J vaccine?

Patients who received the Johnson & Johnson COVID-19 vaccine recently described their symptoms to Business Insider. The symptoms ranged from chills to arm pain, among others.

  • One patient said she got severe chills, shakes and muscle aches hours after getting the Johnson & Johnson vaccine.
  • Another patient said she had chills in the middle of the night and a headache. She was fully recovered by the next night.
  • One patient said she had a high fever, chills and a headache that lasted for five days.
  • One other patient said she felt tired and cold, and she got a fever that lasted for 12 hours.

Which vaccine creates most side effects?

Per Business Insider, fewer people had reactions to the Johnson & Johnson vaccine compared to those who got other vaccines such as Pfizer or Moderna.

Are side effects normal?

The Centers for Disease Control and Prevention has said the vaccine “will help protect you from getting sick with COVID-19. Some people may have mild side effects after vaccination, which are normal signs that your body is building protection against the disease.”

  • Per the CDC, experts suggest that “reactions are an indication that the immune system is responding to the perceived threat — the vaccine — and developing immunity. Coronavirus antibodies should begin to appear about two weeks after the first jab, and maximum protection is obtained about two weeks after the second injection.”
