[Infectious Disease Prevention Group. Update on vaccines, 2020]./ Prevención de las enfermedades infecciosas. Actualización en vacunas, 2020.

Vaccine development is one of the fastest growing sectors in medicine now and in the future, as we are living with the emergency health care for the SARS-CoV-2 coronavirus. The semFYC PAPPS program biannually publishes the recommendations of the group and, in this edition, special emphasis is placed on the common vaccination proposed by the Ministry of Health, where, at last, it no longer discriminates between paediatrics and adults, and proposes a calendar throughout life. The main novelties in the field of vaccinology today are focused on the consolidation of the nonavalent vaccine against the human papilloma virus and in the change of the dose of monovalent meningitis vaccine C for the tetravalent one, ACWY, at age 12. The pandemic we are experiencing has led to the postponement of most preventive activities. On the return to «normality¼, the vaccination calendar must be examined, and completed if necessary.
