Why Do You Take Anhui Zhifei COVID-19 Intensive Needle? What is the best time for the third injection of Anhui Zhifei COVID-19

The best time for the third dose of Anhui Zhifei vaccine

Anhui Zhifei COVID-19 vaccine needs three doses. The specific time interval between the three doses is the interval between the first dose and the second dose, and the interval between the second dose and the third dose is recommended to be 4 weeks or more. The second dose should be completed within 8 weeks after the first dose, and the third dose should be completed within 6 months after the first dose. Can the third dose of Anhui Zhifei vaccine be skipped?

It is not recommended to skip the third dose. Because Anhui Zhifei COVID-19 uses the three needle method for vaccination, the interval between each needle may be different. After two injections, 76% of the antibody can be reached, and after three injections, 97% of the antibody can be reached. So it is necessary to receive three doses.

Is one dose of Anhui Zhifei vaccine effective?

The effect of one dose of Anhui Zhifei vaccine is not very obvious. Generally, a certain amount of antibody is produced after the second dose, and after three doses, the antibody will reach more than 90%.

Why should Anhui Zhifei COVID-19 Vaccine be given three shots

One reason is that the vaccine types are different

Anhui Zhifei COVID-19 Vaccine is a vaccine with recombinant immune protein, and different vaccine methods are different. For example, the inactivated COVID-19 vaccine needs two shots to get immunity, while the adenovirus vector vaccine needs one shot, which can produce effective protection 14 days later.

Reason 2: The effect is more obvious

According to the clinical trial data of Anhui Zhifei recombinant COVID-19 vaccine, the effect of three injections is better than that of two injections, and the neutralizing antibody titer produced is higher, so the three injections method is adopted.

Reason 3: More efficient

Anhui Zhifei COVID-19 vaccine is a recombinant protein vaccine. The safety of this vaccine is relatively high. It is also very efficient and effective to vaccinate three shots. Moreover, the validity period after this is relatively long, which can reach two years.

Reason 4: Relatively strong immunity

After two doses of Anhui Zhifei COVID-19 vaccine, 83% of the vaccinated population can produce neutralizing antibodies. After 3 doses of vaccination, 97% of the vaccinated population can produce neutralizing antibodies.
