How often to take the second dose of COVID-19 vaccine is better

At present, the most commonly used vaccine is the inactivated new coronavirus vaccine, mainly two doses, which can complete the entire vaccination process. After the first dose of vaccination is completed, it is usually separated from the second dose by 3 weeks or even more. However, it is best not to receive the second dose more than 8 weeks after the first dose. Generally speaking, the second dose is best administered within 8 weeks. Usually, after vaccination in this period, most people will produce relatively enough antibodies in the population and can fight against possible external novel coronavirus infection to prevent pneumonia. Therefore, standardized vaccination must be carried out according to time.

The side effects of the second injection of COVID-19 vaccine last for several days

Generally, a few people have been vaccinated with COVID-19 vaccine, and some side effects will appear after the second injection. In most cases, the side effects will last for about 1 to 3 days, and will gradually alleviate and eventually disappear. Usually, there may be local side effects and systemic side effects. The main local side effects are redness, swelling, pain, and hardening of the skin at the vaccination site. The systemic side effects can manifest as fever, headache, dizziness, drowsiness, nausea, vomiting, abdominal pain, diarrhea, and a series of other side effects.

Generally, the side effects are relatively mild, and most vaccinated individuals can tolerate them. Generally, most side effects last for about 1-3 days before they can be completely relieved.
