Who should and shouldn’t get the Moderna vaccine – VnExpress


The World Health Organization’s (WHO) Strategic Advisory Group on Immunization (SAGE) makes several recommendations on the safety and effectiveness of the Covid-19 Moderna vaccine.

The Moderna vaccine, also known as Spikevax, uses mRNA technology, which was approved for emergency use by the World Health Organization (WHO) on April 30. One million doses of Moderna have been delivered to HCMC for vaccination use over the next two to three weeks.

According to SAGE’s updated guidelines at the end of June 2021, the vaccine is more than 90% effective at preventing serious nCoV infections. Its advantage is that there is no need for extreme cold storage, which makes distribution easier, especially in low- and middle-income countries.

According to research by US scientists, Moderna vaccine is highly effective with Delta variant.

Who should be vaccinated first?

As with all vaccines against Covid-19, healthcare workers are at high risk of exposure and the elderly should be given priority for vaccination.

When more vaccines are available, other immunization priority groups need to be added.

Who else can get the vaccine?

Comorbidities (underlying conditions) studied in the phase three clinical trial included chronic lung disease, heart disease, severe obesity, diabetes, liver disease, and immunodeficiency virus infections in HIV people.

SAGE believes that further studies in immunocompromised individuals are needed, but people in this group could be given the shot after information and counseling are provided.

Vaccines can be given to people who have had Covid-19. However, these people can delay vaccination about 6 months from the time of infection.

Vaccine efficacy has been assessed to be similar in breastfeeding women and other adults. SAGE recommends the same vaccine use in breastfeeding women as in other adults. The expert group does not recommend stopping breastfeeding for reasons of Covid-19 vaccination.

Should pregnant women be vaccinated?

SAGE recommends the use of the Covid-19 vaccine in pregnant women when the benefits of vaccinating pregnant women outweigh the potential risks. To help pregnant women make this assessment, information should be provided on the risk of Covid-19 during pregnancy and the benefits of vaccination in the local epidemiological context, and Current limitations on safety data in pregnant women.

SAGE does not recommend diagnostic testing for pregnancy prior to vaccination. The expert group also does not recommend delaying pregnancy or terminating pregnancy for reasons of Covid-19 vaccination.

Who should not be vaccinated?

People with a history of severe allergy to any component of the vaccine should not receive this vaccine or other mRNA vaccines.

Although vaccination is recommended for the elderly because of the high risk of severe Covid-19 and death, very frail elderly people with a prognosis of less than three months of survival need to be assessed on a case-by-case basis.

This vaccine should not be used in people under 18 years of age as results from further studies are not available.

Is this vaccine safe?

On April 30, WHO approved the Moderna vaccine for emergency use. The European Medicines Agency (EMA) has carefully evaluated the data on the quality, safety and efficacy of the Covid-19 vaccine Moderna and has approved it for use in all European Union countries. .

SAGE recommends that all vaccinees be monitored for at least 15 minutes after vaccination. People who experience a severe allergic reaction to the first dose should not get the next dose.

The Moderna vaccine showed about 94.1% protection against Covid-19, starting 14 days after the first dose.

Does this vaccine work with new variants?

Based on the evidence to date, new variants of the virus do not alter the effectiveness of the Moderna mRNA vaccine. It is necessary to continue to monitor, collect and analyze data on new variants and their impact on the effectiveness of diagnosis and treatment.

We do not yet know if this vaccine will prevent infection and prevent transmission of the virus. Immunity lasts for several months but it is not known how long the full duration of immunity lasts. These important questions are being studied.

At the same time, SAGE emphasized that people still have to maintain effective public health measures such as wearing masks, keeping a safe distance, washing hands, respiratory hygiene and the rule of covering coughs and avoiding gatherings. crowded, and ensure good ventilation.

Moderna vaccine in Vietnam

On the morning of July 10, more than two million doses of Moderna vaccine, supported by the US in Vietnam, arrived at Noi Bai airport. These vaccines are part of the 80 million doses of Covid-19 vaccine committed by US President Joe Biden to support a number of countries/territories, including Vietnam, through the Covax program.

Immediately after receiving two million doses of Moderna vaccine, Health Minister Nguyen Thanh Long directed an urgent transfer of one million doses to Ho Chi Minh City.

This is the first batch of Moderna vaccine to Vietnam and the third batch provided by Covax mechanism.

Previously, in April and May, Vietnam received two batches of AstraZeneca vaccine provided by Covax, with a total of about 2.5 million doses. From July 10, Vietnam officially launched the Covid-19 vaccination campaign. , lasting for 9 months, targeting 70-80% of the population.
