The National Institute of Allergy and Infectious Diseases of the United States, which cooperated with Modena to develop a vaccine, studied the first stage immune response of 34 testers and found that the antibodies in their bodies remained relatively high despite a slight decline 3 months after vaccination High level, and there will be no side effects within 2 months.
Side effects of mRNA vaccines are expected.
1. Immediate side effects They include injection arm pain, muscle pain, headache, and fever (15%), which are mild to moderate and relieved within 24-36 hours.
2. Intermediate side effects Generally refers to those possibly happened in 60 days to half a year. We know nothing about this.
3. Chronic side effects, could happened in six months to one or two years or even longer time. We yet have no information about it.
Another unknown is the length of the protective level of antibody concentration. The preliminary result mentioned above is that it will start to decline after 3 months.
