The fourth vaccine is coming! Who can fight? What works best?

As more and more people are diagnosed with COVID-19, and the first dose of booster shot takes too long, the protection has declined. The news of the fourth dose of vaccine broke out recently.

"In June 5438+February 65438+April, the relevant departments issued the" Implementation Plan for the Second Dose of Supplementary Immunization of COVID-19 Vaccine "(hereinafter referred to as the" Implementation Plan "), and the second dose of supplementary immunization can be carried out on the basis of the first dose in the initial stage."

This also means that the fourth vaccine has indeed come, so who can get the fourth vaccine? According to the released inoculation combination, which effect will be better?

First of all, the vaccination population has been clearly stated in the released implementation plan, which basically includes the following four categories:

0 1, people with basic diseases (especially those with serious basic diseases, vaccination is recommended);

02. Infected high-risk groups (such as doctors, nurses and staff in the front line of anti-epidemic);

03, people over the age of 60 (generally speaking, the elderly in everyone's mouth);

04, people with low immunity (simple understanding refers to people who are weak and sick).

However, in view of the recent outbreak of the epidemic, everyone is positive, so we must pay attention to it: the fourth injection will not be given until 6 months after the yang turns negative ~

Secondly, regarding the question of which combination will have better effect, I personally suggest to strengthen the needle aspiration vaccination of Kangxinuo inhaled recombinant COVID-19 vaccine. At present, there are mainly the following nine combinations:

3 doses of inactivated vaccine+1 dose of Kangxinuo intramuscular recombinant COVID-19 vaccine (adenovirus type 5 vector);

Zhifei Longma inactivated vaccine 3 doses +65438+ recombinant COVID-19 vaccine (CHO cells) 0 doses;

3 doses of inactivated vaccine+1 dose of recombinant COVID-19 vaccine (adenovirus type 5 vector) Kangxinuo inhalation;

3 doses of inactivated vaccine+1 dose of Zhuhai Livzon recombinant COVID-19 fusion protein (CHO cell) vaccine;

2 doses of Kangxinuo intramuscular injection adenovirus vector vaccine+1 dose Kangxinuo inhalation recombinant COVID-19 vaccine (adenovirus vector type 5);

3 doses of inactivated vaccine+1 dose of Chengdu Wisconsin recombinant COVID-19 vaccine (sf9 cells);

3 doses of inactivated vaccine+1 dose of Beijing Wan Tai nasal spray influenza virus carrier COVID-19 vaccine;

3 doses of inactivated vaccine+1 dose of Zhejiang clover recombinant COVID-19 protein subunit vaccine (CHO cells);

Three doses of inactivated vaccine+1 dose of recombinant COVID-19 bivalent S trimer protein vaccine from Shenzhou cells.

The reason why I recommend three doses of inactivated vaccine plus1dose of recombinant COVID-19 vaccine (adenovirus type 5 vector) for Kangxinuo inhalation is not that any authoritative organization or media has proved that it is much better than other combinations, but that friends around me have vaccinated it, and the feedback effect is good. I don't know others very well, and I dare not recommend them rashly.

Specific to individuals, which combination vaccine to vaccinate depends on the actual situation. The medical institution will give advice based on your vaccination history and vaccine inventory.

In any case, in this big environment, friends are advised to wear masks when going out, wash their hands frequently every day and remember to ventilate their homes. Try not to go out, let alone eat or travel. Earn more money, save more money and take care of yourself and your family more than anything else.
