Impact of the COVID-19 pandemic on routine childhood immunisation in Colombia.

Objective: To assess the impact of the COVID-19 pandemic on routine childhood vaccination coverage in Colombia by age group, rural/urban residence, state and vaccine type.

Design: Ecological study of official monthly vaccination records.

Setting: Vaccination records from the Colombian Ministry of Health (March-October 2019 and 2020).

[Pentavalent vaccine and vaccination coverage in children aged less than one in Colombia 2000-2003].

Objective: Determining the impact of including pentavalent vaccine in third-dose immunisation coverage for children aged less than 1 (2002 and 2003) by geographic cluster.

Materials And Methods: This was an ecologic study using department, province, municipality and capital city as analysis units. It compared third-dose coverage, desertion index, number of places having more than 80% immunisation coverage and the number of children being immunised before and after vaccination was introduced.
