(e.g. 2012 = 2013 report).

Given these, the total number of Filipinos infected by dengue from 20122016 was 900,089.

- ure (80 percent of 200,000) to include people who are infected by dengue but aren’t showing any symptoms (asymptomat­ic cases).

A more reliable multiplier in order to include asymptomat­ic cases is the adjustment factor computed by Dr. Frances E. Edillo et al. in their 2015 study published in the AmericanJo­urnal titled “Economic Cost and Burden of Dengue in the Philippine­s.”

The adjustment factor is 7.2, which means for every 1 reported case there are 7.2 actual dengue infections. So, from 2012 to 2016, the estimated number of all dengue infections is 6,480,641 (900,089 x 7.2).

The figure 6,480,641 is only 5.8 percent of our population in 2015 (i.e. 110,981,437). Thus, the estimated population percentage that are seropositi­ve (infected by dengue) is not 90 percent, as Aquino falsely claimed, but around 5.8 percent. That means, around 94.2 percent are probably seronegati­ve (not infected by dengue) when he approved the mass vaccinatio­n.

Third, Aquino’s computatio­n of how many seronegati­ves there were among the Dengvaxia vaccinees at risk of severe dengue is also wrong.

His estimate of .02 percent of 10 percent of 1 million is inaccurate. Ac-
