We can see the development of COVID-19 epidemic, the constant variation of COVID-19 virus strain and the recurrence of epidemic. In this case, we can see that the best defense method is to vaccinate COVID-19 vaccine according to our actual situation. Our domestic COVID-19 vaccine is very effective and safe, and it has also been recognized by the World Health Organization and many countries in the world.
For viruses without mutation, our COVID-19 vaccine has a very high protection rate. Even in the face of mutated COVID-19, our domestic COVID-19 vaccine still has a high protection rate. Besides, even if we are infected with COVID-19 vaccine, the symptoms are much milder. In many cases, we can avoid serious diseases or even death. Therefore, COVID-19 vaccination is useful and can protect us well.
People who have not been vaccinated with COVID-19 vaccine should be vaccinated with COVID-19 vaccine according to their actual situation. This is the best way of self-protection at present, and it is also a citizen's sense of social responsibility. What is certain now is that everyone should take precautions, pay close attention to the latest epidemic situation in COVID-19, do a good job in personal hygiene, wash hands frequently, open windows for ventilation, pay attention to hygiene, minimize cross-regional mobility, and strictly enforce epidemic prevention regulations when not gathering in public places.
