Corona virus vaccine maker Pfizer has started trials of its vaccine on children under the age of 12. In the Phase I study, a small number of young children will be given different doses of the vaccine. For this, Pfizer has selected more than 4500 children in four countries of the world. The countries where Pfizer’s vaccine is to be tested on children include the US, Finland, Poland and Spain.
Vaccines already being administered to children above 12 years of age
Pfizer’s COVID vaccine has already been approved for use in children over the age of 12 in the US and European Union. However, this approval has been given for emergency use only. Pfizer made this corona vaccine in collaboration with its German partner BioNtech. The vaccine of this company was first approved by the World Health Organization.
Trial soon on children above 6 months of age
The company said that the work of enrolling children aged 5 to 11 years will be started this week for the vaccination trial. These children will be given two doses of 10 micrograms each. This dose is one-third of the vaccine dose given to adolescents and adults. A few weeks after this, the vaccine trial will be started on children above 6 months of age. They will be given three micrograms of vaccine.
Many companies in the field
Apart from Pfizer, Moderna is also conducting a vaccine test on 12-17 year olds and the results may be out soon. The special thing is that the FDA has given permission to test the vaccine on children up to 11 years of age, relying on the results of both the companies so far. Last month AstraZeneca launched a study in the UK on children aged 6 to 17 years. At the same time, Johnson & Johnson is also studying. China’s Sinovac has also described its vaccine as effective on children up to 3 years old.
