While 79% of people worldwide "somewhat" or "strongly agree" that vaccines are safe, certain parts of the world have a concerning level of disbelief, particularly in parts of Europe, according to a large Gallup survey for charitable foundation Wellcome Trust released on Wednesday.

Why it matters: The global health community is trying understand and combat pockets of anti-vaccination or vaccine hesitancy, which have recently led to some devastating outbreaks, such as from the highly contagious but preventable measles, even though vaccine injuries are rare.

Details: Wellcome says this "first-of-[its]-kind global survey" asked more than 140,000 people aged 15 and older in 144 countries various questions last year to determine how they think and feel about health and science, including vaccination.

By the numbers: Per Wellcome Global Monitor 2018, when asked their position on whether "Vaccines are safe," respondents indicated...

  • Globally: 79% agree that vaccines are safe, 7% disagree, 11% neither agree nor disagree, and 3% don't know.
  • North America: 72% agree, 11% disagree, 16% neither agree nor disagree, 1% don't know.
  • Eastern Europe: 50% agree, 17% disagree, 26% neither agree nor disagree, 7% don't know.
  • France: Showed the highest percentage of people who disagree vaccines that are safe, at 33%.
  • Bangladesh and Rwanda: Showed the highest percentage of people who agree vaccines are safe, at 97% and 94% respectively.
  • Of note: "Agree" and "disagree" combine both ranges of "somewhat" and "strong."

Between the lines: Wellcome's report says France's vaccine skepticism was found to be consistent throughout the various demographics as "it does not vary significantly by education, age, gender, urban or rural status, or whether people are parents."

  • The report notes that researchers have found there was a a substantial increase in vaccine skepticism in France after the pandemic H1N1 influenza vaccination campaign in 2009, which had stirred up some controversy that was refuted by the World Health Organization.
  • "The rising vaccine hesitancy in France over the past several years — which even now includes some members of the medical community — has helped drive vaccine coverage among some children and young adults below immunity thresholds and led to rising numbers of measles and meningococcal disease cases," the report states.

Methodology: This study was included in the Gallup World Poll and was translated into the major languages of each country. 3,600 interviewers in the 144 countries used face-to-face and phone interviews to collect the data from April to December 2018. Here's their methodology and their questionnaire.

Zeta, classified as a "significant" Category 2 hurricane, made landfall along the southeastern coast of Louisiana on Wednesday evening, according to the National Hurricane Center.

The state of play: Louisiana Gov. John Bel Edwards (D) requested a pre-landfall Emergency Declaration in a letter to President Trump on Tuesday. The hurricane is producing 110-mph maximum sustained winds and stronger gusts. The core of Zeta — including its destructive eyewall — moved ashore near Cocodrie.

Supreme Court won't expedite Pennsylvania GOP's request to block mail-in ballot extension

The Supreme Court voted 5-3 on Wednesday to deny a bid from Pennsylvania Republicans to expedite their request to shorten the deadline for receiving mail-in ballots. Newly-confirmed Justice Amy Coney Barrett did not participate in the decision.

Why it matters: A lower court ruling allowing ballots to be counted until 5 p.m. on Nov. 6, as long as they are postmarked by Election Day, will remain in place for now. Conservative Justices Alito, Thomas and Gorsuch wrote in a separate opinion that it's too close to the election to take up the case, but it could still be reviewed after the election if late-arriving ballots make a difference.
