World Immunization Week

Celebrated on Last Week of April Each Year, World Immunization Week

World Immunization Week is celebrated every last week of April each year. This weeklong event aims to promote the use of vaccines in order to protect us, humans, from various kinds of diseases. There are different kinds of vaccine-preventable diseases in our world. While we have been successful in making ourselves immune from these diseases due to vaccination, there are still some people who don’t get these vaccine shots primarily due to lack of access or lack of information. Hence, World Immunization Week aims to solve these problems by expanding the coverage of immunization as well as informing the people regarding the facts about it.

Facts about vaccines

The following are the key facts about vaccines:

  • The safest way to protect against disease is vaccination – getting vaccinated against various diseases is 100 percent safe. Numerous researches, scientific studies, and clinical trials have demonstrated that vaccines do not harm our bodies. They do the exact opposite by protecting us whenever infectious disease enters our bodies. They fight those infections so that we can stay healthy and disease-free.
  • Even when you are at low risk of getting a disease, it is always best to be vaccinated – polio is one of the deadly diseases that wreaked havoc in the world that was totally killed by vaccination. Before, a lot of people either get killed or became disabled because of the poliovirus. When a vaccine against it was invented, the rate of the infection quickly went down. It became an extremely effective measure against the disease. However, even if the rate of infection is now nil, you still want yourself to be vaccinated against the disease. These viruses still linger in our environment and you want yourself to be protected against them. Hence, you must get all the vaccines that you can get in order to protect yourself from catching these diseases.
  • Multiple vaccine shots are not harmful – some people get scared by the fact that we need to take different vaccines for protection against different diseases. Most of these vaccines are given all at the same time. There is no harm to thus contrary to what some people may think. Getting vaccinated multiple times is 100 percent safe.
  • Vaccination is not linked with autism – there are people who campaign against vaccines and one of their prime argument is that it increases the risk of autism. However, there is NO scientific evidence that supports this. There was actually one study that proposed this back in 1998. It was later on found to be seriously flawed and got retracted form the journal in which it was published.
  • Eliminating vaccination will resurrect deadly diseases – there is another important fact that we must take into account. If a lot of people stop getting vaccines, the deadly diseases that have been feared before will make a return. Recently, there have been reports of a resurgence of poliovirus due to people failing to get vaccine shots. If this continues on, an outbreak is possible. And it is not only probably for this disease, there are hundreds or more of infectious diseases that could substantially spread of people altogether stop getting vaccinated.


It was in May 2012 when the celebration of World Immunization Week was first endorsed by the World Health Assembly. There were some countries having this celebration beforehand but there were held in different dates. Hence, the World Health Assembly thought of making an international celebration in a specific date. The date of the last week of April was chosen. The first-ever celebration was participated by more than 180 countries all around the world.
