Get the facts about the Covid-19 vaccine

Currently there are vaccines for 24 infectious diseases, some of which we receive early in our lives while others are given later on in life, due to age, travelling plans, or during a pandemic such as with the COVID-19 vaccines.

With the introduction of the new SARS-CoV-2 vaccines across Ireland and the world, there has been widespread lack of confidence when it comes to the safety of immunisation and vaccine jabs. Whilst each of us are our own best advocates for our health, we need to take the advice of medical professionals and scientists around the world into account, before making vital health decisions.

With so much information online, on social media, and spreading through word of mouth, it can be difficult to know exactly what to believe.

We have answered a few frequent queries around the safety of vaccines, so you'll be able to make a more educated decision when it comes to having a flu vaccine, the COVID-19 vaccine, or any other vaccine you may be offered.

Do vaccines work?

YES vaccines do work! Vaccines are heroic in protecting the population from mass disease. Immunisation through vaccines prevents millions of deaths every year, from diseases like measles and influenza (flu). We can see that vaccinations perform well in eradicating diseases by looking at both past and present evidence.

.

Before the 1963 implementation of the measles vaccine, significant epidemics occurred every 2 to 3 years, resulting in about 2.6 million deaths a year. worldwide. Since the measles vaccine was launched, the disease has been decreased by 99.9%. Measles vaccination has avoided an estimated 23.2 million deaths between 2000 and 2019, a figure that would be much higher if universal vaccination were accessible.


Following the rollout, we can already see that the COVID 19 vaccines are working, as shown by a decline in people contracting the virus, as well as people needing hospitalisation and dying from the disease.


How do vaccines work?

Vaccines operate by injecting a killed, inactivated, damaged, or partial form of the pathogen into your body to prime your immune system for potential contact with the disease. When you get a vaccine, the immune system is stimulate
