Pertussis vaccine for adolescents and young adults.

In the industrialized countries, vaccines are provided either by the government or under the medical insurance schemes. In our country, cost of vaccines (not included in national schedules) is borne by the people. Adolescents and young adults belonging to low economic groups are more prone to get pertussis infection because of overcrowding but may not be able to afford currently available Tdap vaccine. An infected person spreads the infection even before developing the symptoms of the disease himself/herself. Thus, this section of the society needs to be provided protection against pertussis so that young children and old people in the community who come in their close contact are not exposed to pertussis infection. IAP should urge the government of India to subsidize Tdap or provide it through national programs.
