Is the COVID-19 inactivated vaccine effective against Delta virus?
Answer: Laboratory data and some real-world studies have shown that China's biologically inactivated vaccine is still effective against mutant strains such as Delta
China Biosciences has also been closely monitoring the mutation of the COVID-19 virus. The research and development of inactivated vaccines against the mutant strains and delta mutant strains found in South Africa are in progress. At present, the materials have been submitted to the regulatory authorities on a rolling basis and will be approved after approval. Announce progress to the public in a timely manner.
The COVID-19 inactivated vaccine developed by China Biologics is produced using a safe inactivation process for the whole virus, and the inactivation process maintains the diversity of virus antigens. Vaccination with inactivated vaccines can simulate the process of COVID-19 virus infection in the body and stimulate the body to produce broad-spectrum antibodies. Therefore, the COVID-19 inactivated vaccine has the advantages of broad antigen spectrum and resistance to mutant strains.
How to prevent the delta strain?
1. Actively vaccinate against COVID-19
Vaccination is the most effective measure to prevent diseases. Don't miss vaccination because of travel.
2. Adhere to normalized epidemic prevention and control measures
Wear masks scientifically, wash your hands frequently, ventilate frequently, and try not to go to crowded places with poor air circulation. Consciously comply with the epidemic prevention measures, and cooperate with the prevention and control measures such as wearing masks, checking codes, temperature measurement, and one-meter noodles in public places such as shopping malls, supermarkets, hotels, theaters, stadiums, buses, subways, and airport waiting rooms.
3. Maintain a healthy lifestyle
Clothes should be added or removed in time according to temperature changes; attention should be paid to the combination of work and rest, and regular work and rest
4. Continue to insist on not going out of the country if it is not necessary, and not to travel or travel to medium-high-risk areas, tourist hotspots, or business trips.
5. Reduce unnecessary gatherings.
It is not suitable to hold or participate in gatherings with large numbers of people. Avoid gatherings in confined spaces. Keep the activities as brief as possible and pay attention to opening windows for ventilation. Participants should take personal protection, keep a safe distance from others, and prevent sick gatherings.
