Interactive maps produced by Radio-Canada from Montreal Public Health data show where vaccination rates on the Island of Montreal are lagging. The Quebec government’s target is to have at least 75 percent of the population vaccinated. Of the 3,000 sectors on the map, 70 percent have reached that goal for the first dose and 3 percent for the second.

These data are useful in terms of where to target mobile clinics and other vaccination outreach programs. I’d love to see this for other cities in Quebec, especially the one nearest to me: Gatineau’s current rate is relatively low (66.4 percent first dose, 51.2 second dose as of this week) and it’d be revealing to see where the uptake is stronger or weaker.

Maps tracking the progress of the U.S.’s COVID-19 vaccination campaign at the CDC’s COVID Data Tracker (now) include an interactive county-level map showing first and second doses among 12+, 18+ and 65+ populations and a map of vaccine equity (above): a bivariate choropleth map showing the relationship between vaccination coverage and social vulnerability (housing, vehicle access, general poverty).

This interactive map compares U.S. COVID vaccination rates with active cases at the county level. Created by McKinsey and Company’s COVID Response Center, it’s a bivariate choropleth map that shows two variables at once. (If this confuses you, the legend helps.) It’s a good way to see where low vaccination rates correlate with lots of COVID cases (red on this map), or high vaccination rates with few cases (teal); the map lets you explore other variables as well.

The Centers for Disease Control and Prevention released data and maps showing the estimated rate of COVID-19 vaccine hesitancy in the U.S. on a county-by-county basis. The data is based on a question in the Census Bureau’s Household Pulse Survey that asked respondents whether they’d get a vaccine for COVID-19 once it was available to them.

Now that vaccines are available, they can be mapped as well. The U.S. Centers for Disease Control’s COVID Data Tracker includes this map of total doses administered in the U.S.; this NBC News county-level map showing the percentage of Americans living within 50 miles of a pharmacy expected to carry a vaccine dates from December and is probably out of date by now.

According to a survey, more than a quarter of the U.S. population would not get a COVID-19 vaccine if it was available to them. This number is not evenly distributed: this map from MIT Technology Review, presented as a map showing whether your neighbours want to get vaccinated, reveals the regional pockets of vaccine hesitancy (see above). (What the actual hell, Louisiana?)

The New York Times maps confirmed measles cases in the United States as of April 29, 2019. “Measles was declared eliminated in the United States in 2000 but the highly contagious disease has returned in recent years in communities with low vaccination rates. The number of cases reported this year is already nearly double last year’s count and has surpassed the previous post-elimination high of 667 cases in 2014.”
