Live Q&A on #COVID19 vaccines with @doctorsoumya and @Kate_L_OBrien. #AskWHO pscp.tv/w/cnqxzzI2MTAy…

Our body has many ways of defending itself against pathogens such as
 
💪Physical barriers that prevent them from entering the body
💪Immune systems that destroy them once they infect our body
 
Learn about how #VaccinesWork ➡️bit.ly/3efxPJe

When a 🆕 pathogen/disease enters our body, it introduces a new antigen.
 
Our body then produces antibodies that work with the rest of the immune system to destroy the antigen and stop the disease.

How do #VaccinesWork?
 
1⃣Vaccines contain weakened non-dangerous parts of an antigen
2⃣It's enough that our body can learn to build the specific antibody
3⃣This will prompt our immune system to respond & defeat the real antigen in the future

Antigen is the 🗝️ ingredient in a vaccine. It's either a tiny part of the disease-causing organism, or a weakened, non dangerous version.
 
It's tiny enough that our body can learn to fight the virus without getting sick. Learn more 👉bit.ly/2TPACiE #VaccinesWork

Vaccines help to protect us by enabling our bodies to produce antibodies ahead of potential infection.

Vaccines go through 3 testing phases before they can be approved:
 
1⃣ Small scale safety trials
2⃣ Expanded safety trials
3⃣ Large scale efficacy trials
 
The number of volunteers around🌎🌏🌍 increases at each stage to assure #VaccinesWork for many different populations.

Vaccine-preventable diseases include

Cervical cancer
Cholera
Diphtheria
Ebola
Hep B
Influenza
Japanese encephalitis
Measles
Meningitis
Mumps
Whooping cough
Pneumonia
Polio
Rabies
Rotavirus
Rubella
Tetanus
Typhoid
Varicella
Yellow Fever
Yes, #VaccinesWork!

People with underlying health conditions may not be able to be vaccinated but they can still be protected.
 
💪If you are able to, get vaccinated. Herd immunity helps to protect everyone.

Humans have successfully developed vaccines for a number of life-threatening diseases, including meningitis, tetanus, measles and polio.
