Side effects after the COVID-19 vaccine are caused by your immune system. But a lack of side effects doesn't mean your COVID-19 vaccine didn't work.
Common symptoms include local pain, redness, swelling, systemic tiredness, headache, muscle pain, fever, and nausea. Regulating authorities are suggesting facial paralysis and swelling as possible orofacial adverse effects of the COVID-19 vaccine, which is assumed to occur rarely [6].
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.
Reports of death after COVID-19 vaccination are rare. FDA requires healthcare providers to report any death after COVID-19 vaccination to the Vaccine Adverse Event Reporting System (VAERS), even if its unclear whether the vaccine was the cause.
Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.
Possible side effects: Pain, redness, or swelling at the site where the shot was administered, and/or tiredness, headache, muscle pain, chills, fever, or nausea throughout the rest of the body. If these side effects occur, they should go away in a few days. A few side effects are serious, but rare.
These cases typically occur in male adolescents and young adults after the second dose, and within a week of vaccination. It is important to seek medical care if symptomatic (chest pain, shortness of breath, having a fast beating, fluttering, or pounding heart).
mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV). As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.
No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.
Conclusions The findings suggest that compared with a third dose of mRNA covid-19 vaccine, a fourth dose improved protection against infection, symptomatic infection, and severe outcomes among long term care residents during an omicron dominant period.
Monitoring of the Moderna COVID-19 vaccine has found 10 cases of anaphylaxis after the administration of 4,041,396 first doses of the Moderna COVID-19 vaccine. In 9 out of these 10 cases of anaphylaxis, the recipient of the vaccine had onset of symptoms within 30 min of administration.
According to the University of California Davis Health, the reported symptoms of BA. 5 are similar to previous COVID variants: fever, runny nose, coughing, sore throat, headaches, muscle pain and fatigue.
COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).
3,700 participants answered the blood type question and 2,878 individuals knew their blood type and were vaccinated. By Kruskal-Wallis test, there was no statistically significant association between any reported blood type and any side effect for either dose of either vaccine product.
Monitoring of the Moderna COVID-19 vaccine has found 10 cases of anaphylaxis after the administration of 4,041,396 first doses of the Moderna COVID-19 vaccine. In 9 out of these 10 cases of anaphylaxis, the recipient of the vaccine had onset of symptoms within 30 min of administration.
Symptoms include chest pain, palpitations (the feeling of one's heart beating very fast), and shortness of breath. If your child develops any of these symptoms after receiving the COVID-19 vaccine, please contact your pediatrician and seek medical care.
