Introduction
Since January, COVID-19 vaccines have been part of the national vaccination program, prioritizing groups based on age and health status. According to Professor Max Igor Banks, an infectious disease specialist at the Hospital of the Faculty of Medicine of the University of São Paulo, it’s crucial for children up to five years, the elderly over 60, people with co-morbidities, and those who are immuno-suppressed to receive a Covid-19 booster shot. This booster can be administered every six months or annually. Professor Banks also highlights the importance of vaccinating pregnant women, as this protects both the mother and the baby. Additionally, those who have never been vaccinated before should take immediate action to get their shots.
Understanding Vulnerable Groups
Definition of Vulnerable Groups
Vulnerable groups include individuals who are at a higher risk of severe illness from COVID-19. This category encompasses young children, the elderly, those with underlying health conditions, immuno-suppressed individuals, pregnant women, and people who have not yet been vaccinated.
Why They Are at Higher Risk
These groups are more susceptible to severe complications from COVID-19 due to weaker immune systems, pre-existing health conditions, or increased exposure risks. For them, contracting COVID-19 can lead to more severe health outcomes, prolonged recovery times, and higher mortality rates.
Children Up to Five Years
Risks and Benefits of Vaccination for Young Children
Young children are at risk of severe Covid-19 symptoms due to their developing immune systems. Vaccinating them helps reduce the severity of the disease, prevent hospitalization, and curb the spread of the virus.
Expert Opinion: Professor Max Igor Banks
Professor Banks emphasizes that vaccinating young children is crucial for their safety and health. He suggests that a booster dose should be administered regularly to ensure continued protection against evolving Covid-19 variants.
Elderly Over 60 Years
Increased Susceptibility to Severe Covid-19
The elderly are particularly vulnerable to severe Covid-19 symptoms and complications due to age-related decline in immune function. They are more likely to experience critical illness, hospitalization, and death.
Long-term Benefits of Booster Doses
Regular booster doses help maintain a robust immune response in the elderly, reducing the risk of severe outcomes and enhancing overall health and longevity.
People with Co-morbidities
Common Co-morbidities and Their Impact
Individuals with co-morbidities such as diabetes, heart disease, and respiratory conditions face higher risks when contracting Covid-19. These underlying health issues can exacerbate the severity of the disease.
Necessity of Regular Booster Doses
For those with co-morbidities, regular booster doses are essential to strengthen their immune defenses and minimize the risk of severe illness and hospitalization.
Immuno-suppressed Individuals
Challenges Faced by Immuno-suppressed People
Immuno-suppressed individuals, including those undergoing chemotherapy or living with HIV, have compromised immune systems that struggle to combat infections effectively.
How Boosters Enhance Their Protection
Booster doses are particularly vital for immuno-suppressed individuals as they provide an additional layer of defense, helping their bodies better fight off the virus and reducing the likelihood of severe illness.
Pregnant Women
Importance of Vaccination During Pregnancy
Vaccination during pregnancy is crucial as it protects both the mother and the unborn baby. Covid-19 can cause severe complications in pregnant women, including preterm birth and severe illness.
Protection for Both Mother and Baby
Vaccinating pregnant women ensures that antibodies are passed on to the baby, offering protection during the early months of life when the baby’s immune system is still developing.
Unvaccinated Individuals
Risks of Remaining Unvaccinated
Unvaccinated individuals remain highly vulnerable to severe Covid-19, especially with the continuous emergence of new variants. Their risk of hospitalization and death is significantly higher compared to vaccinated individuals.
Steps to Take Now for Better Protection
It is imperative for those who haven’t received their Covid-19 vaccines to get vaccinated as soon as possible. This not only protects them but also helps reduce the spread of the virus in the community.
Evolution of the Covid-19 Vaccine
From Monovalent to Bivalent Vaccines
The initial COVID-19 vaccines were monovalent, targeting the original strain of the virus. As new variants emerged, vaccines were updated to bivalent models, which protect against both the original virus and new variants like Omicron.
Updates with the Arrival of New Variants
The evolution of the virus necessitated updates to the vaccines. Bivalent vaccines now offer broader protection, making them more effective against current and emerging strains.
The Role of Omicron Variant
How Omicron Changed the Vaccine Landscape
The Omicron variant’s high transmissibility and mutations prompted significant changes in vaccine formulations. This led to the development of bivalent vaccines that can better combat Omicron and its subvariants.
Bivalent Vaccines for Better Protection
Bivalent vaccines provide enhanced protection by targeting multiple strains of the virus, thereby improving overall immunity and reducing the severity of breakthrough infections.

Introduction of New Vaccines
Moderna’s SpikeVax and Pfizer’s Updates
Moderna’s new SpikeVax no longer uses the bivalent model and is designed to protect against the latest variant, XBB. Pfizer has also updated its vaccines to offer better protection against current circulating strains.
Protection Against the Latest Variants
These new vaccines are crucial in ensuring that individuals remain protected against the latest variants of COVID-19, reducing the risk of severe illness and hospitalization.
Current Vaccination Strategies
Government’s Targeted Vaccination Project
The government’s current vaccination project targets vulnerable groups, ensuring they receive the necessary booster doses to stay protected. This strategic approach helps manage vaccine supply and maximize public health benefits.
Availability of Vaccines in SUS
Vaccines are readily available in the public health system (SUS), making it easier for people in priority groups to access their booster doses and stay protected.
Timing and Strategy
Ideal Time for Getting Vaccinated
Now is an ideal time to get vaccinated, as there is no intense spread of the virus. Getting a booster dose now ensures protection before potential future outbreaks.
Preparing for Potential Future Outbreaks
By vaccinating during periods of low transmission, individuals can build immunity that will protect them when the virus circulation increases again, reducing the overall impact of future outbreaks.
Expert Insights
Professor Banks’ Views on Vaccination Timing
Professor Banks advises that getting vaccinated during periods of low transmission is strategic, as it prepares the immune system to handle future surges in virus circulation.
Long-term Strategy for COVID-19 Prevention
A long-term vaccination strategy, including regular booster doses, is essential for maintaining public health and preventing severe illness, especially among vulnerable groups.
Conclusion
Vaccinating vulnerable groups with booster doses is crucial in the ongoing fight against Covid-19. As the virus continues to evolve, staying up-to-date with vaccinations helps ensure the best possible protection. If you belong to a high-risk category, make sure to get your booster shot now to safeguard your health and the health of those around you.
FAQs
Why are booster doses necessary now?
Booster doses are necessary to maintain high levels of immunity, especially as new variants of Covid-19 continue to emerge. They help ensure vulnerable groups remain protected against severe illness.
