Trend in the availability of vaccines in Brazil: PMAQ-AB, 2012, 2014, and 2018].

The objective was to analyze the trend in the availability of vaccines in Brazil and its various regions and states from 2012 to 2018. This cross-sectional study used data from basic units assessed in cycles I (2012), II (2014), and III (2018) of the Brazilian National Program for Improvement of Access and Quality of Basic Care (PMAQ-AB). We assessed the availability of the dT, hepatitis B, meningococcal C, polio, pneumococcal 10-valent, MMR, DPT, tetravalent/pentavalent, and human rotavirus vaccines. Identification of trend was performed with weighted least squares regression to estimate annual percent changes. We also verified the relative and absolute differences in prevalence of vaccines. The sample consisted of 13,842 basic health units in Cycle I, 19,752 in Cycle II, and 25,152 in Cycle III. An upward trend was seen in the prevalence of availability of all vaccines investigated during the period, with an increase of 16 percentage points from 2012 to 2018, reaching nearly 70% in 2018. The regions with the largest upward trend were the North (2.9p.p.), Central-West (2.1p.p.), and Northeast (2.0p.p.). There was a visible downward trend in both the availability (-3.3p.p.) and absolute and relative difference (-20p.p.; 0.68) in Rio de Janeiro State. The prevalence of availability of vaccines was low in Brazil, with disparities between regions that become even more pronounced when assessing specific states.
