In the 4th month the baby receives:
A- The second dose of vaccine against Poliomyelitis (the drop);
B- The second dose of Tetra vaccine, against Diphtheria (Croup), Tetanus, Whooping Cough and other infections caused by Hemofilus (Meningitis and others);
C- The second dose of vaccine against Rotavirus (the drop).
Some vaccines need to be taken more than once for them to have an efficient and lasting effect. Therefore, it is important that the babies take all vaccine doses prescribed. Thus, if they catch any of those diseases against which they are vaccinated, the disease will come much lighter.
In the Vaccination Campaigns, extra doses of vaccines are given. It is important to participate in those campaigns so the diseases are controlled!
