How long is the protection period after COVID-19 booster vaccination? Can wearing a mask prevent COVID-19 transmission

How long to manage after COVID-19 vaccination

At present, phase I and II clinical subjects are still continuing to observe. From the data obtained, it can be maintained for at least 6 months, meeting the requirements of the World Health Organization. The earliest vaccinated individuals have been monitored for over 8 months, and the results show that it is still effective. With the extension of the observation period and the accumulation of research data, protection periods exceeding 6 months or even longer may continue to be confirmed.

What are the precautions for vaccination

Before vaccination:

Recipients should know about COVID-19 vaccination, carry relevant certificates (ID card, passport, etc.), wear loose clothes on the day of vaccination to facilitate vaccination, and wear masks at the vaccination clinic.

During vaccination:

Cooperate with on-site vaccination staff to inquire and truthfully provide information such as personal health status and vaccination contraindications.

After vaccination:

must stay in the observation area for 30 minutes until there are no abnormal conditions before leaving. Keep the local skin clean during vaccination and avoid scratching the vaccination site with your hands; If discomfort symptoms such as fever and rash occur, please seek medical attention promptly and report to the vaccination unit.

This vaccination will be arranged through a combination of industry unit plans and individual appointments. Personnel from related industries and collective units can make appointments for vaccination through the unified arrangement of the unit. Other personnel can make appointments for vaccination themselves according to the appointment method announced by the vaccination clinic. After the appointment is successful, they can bring their ID card to the appointment clinic for vaccination on time. Each vaccination unit will equip a sufficient number of qualified and trained vaccination personnel in accordance with regulations, strengthen health inquiries during the vaccination process, strictly control contraindications, standardize vaccination services, and ensure vaccination safety.

Can you still be infected with coronavirus by wearing a mask

Patients who wear a mask to contact with novel coronavirus infection may also be infected, and wearing a mask will reduce the infection of COVID-19. There are three transmission routes of COVID-19, namely, respiratory droplets and close contact, which are the main transmission routes. In a relatively enclosed environment, prolonged exposure to high concentrations of aerosols may result in the possibility of aerosol transmission.

When contacting patients infected with novel coronavirus, although they wear masks, they can effectively block droplets in the air, thus reducing the risk of droplet transmission. However, if you touch patients infected with novel coronavirus, if you rub your eyes with your hands, you may also be infected.

Since novel coronavirus can be isolated from feces and urine, attention should be paid to environmental pollution of feces and urine, resulting in aerosol or contact transmission. These three transmission routes are all caused by droplets or aerosols, so wearing a mask can reduce the spread of droplets and minimize the impact of aerosols on respiratory tract infections. Since the main source of infection is COVID-19 infected patients and asymptomatic infected people, asymptomatic infected people may also exist in the crowd, so masks must be worn in public places to reduce infection.
