New guide to evaluating vaccines for young children

Story highlights COVID-19, which targets particulate matter above 25microns, was effective for children only.

Finding effective symptoms in children is even more complicated.

Finding effective and safe vaccines for young children is no easy task. They are especially vulnerable to serious and even fatal health complications if they are not fully vaccinated. This is not due to the reduced survival rates from vaccine-preventable diseases. It’s due to the complexity and rarity of vaccine-preventable illnesses.

Most common vaccine preventable illnesses in children in North America involve the following three families: pertussis (whooping cough), mumps and polio.

The whooping cough vaccination is the most effective vaccine available against this disease, which attacks the respiratory system. But this aspect of the vaccinations is actually what creates the problem. When not enough of the pertussis vaccine is administered to young children (due to parents’ concerns about the Pertussis Diphtheria and Tetanus (DPT) vaccine’s safety), we get an increased risk of a pertussis outbreak.

Highly immunized populations in one area, such as universities and hospitals, are also at risk for heightened pertussis transmission and outbreaks.

The mumps vaccination also causes side effects; individuals can experience an ear infection, swelling of the testicles and sometimes even meningitis. But the mumps vaccine is highly effective and must be considered if you are concerned about this infectious disease, which still causes significant illness and even death in adults.

Although few vaccines protect children completely from possible problems with health care delivery, the polio vaccine prevents polio, which causes muscle weakness and weakness on one side of the body, and paralysis. A separate polio vaccine protects people from how the polio vaccine itself is immunogenic.

Due to the few other known complications associated with vaccines, it’s important to consider doses of these vaccines, because no individual vaccines are 100% effective, and the most effective vaccines protect the most children and the most people.

For children of all ages, the best strategy for immunization is the vaccine most effective against the diseases they are most likely to get. For example, the MMR (measles, mumps, rubella) and the DPT (whooping cough) vaccines protect against many diseases, while the combined poliovirus and enterovirus (polio) vaccine protects against two diseases that most children will probably get.

Under a new policy, the City of Toronto’s policy direction is to provide “sufficient immunity to all children before they receive the vaccines recommended for their age,” meaning the combination of all vaccines is becoming less effective for these children.

That means, for all children aged 5 to 11, vaccines recommended by the United States Centers for Disease Control and Prevention or the World Health Organization will no longer provide 100% immunity. Instead, children should be vaccinated with a single-dose vaccine. These vaccines also include immunity against all known diseases, such as measles, and are stronger against cervical and shingles, which is a neurological disease where a nerve damage in the skin of the cervix causes painful sores in the area of the cervix and can cause permanent scarring.

This is only a guide; because each disease affects different individuals in different ways, the efficacy of vaccines varies. If you have questions about vaccinations, visit the Toronto Public Health Immunization webpage.
