Question 1

What temperature ranges does the mobile vaccine transport trailer support?

Accepted Answer

Standard configurations include: +2°C to +8°C (refrigerator range, most common for vaccines like polio, measles, DTP, hepatitis), -20°C (freezer range, for varicella vaccine and some biologics), -70°C ultra-cold (for COVID-19 mRNA vaccines from Pfizer-BioNTech and similar products requiring deep cold storage). Multi-zone configurations allow simultaneous transport of vaccines requiring different temperature ranges in separated compartments.

Question 2

How is cold-chain compliance documented?

Accepted Answer

Continuous temperature monitoring at multiple positions through the cargo compartment with logging at 1-5 minute intervals, audit-trail records preserved per WHO PQS requirements (typically 3+ years record retention), temperature excursion alarms during transport, and chain-of-custody documentation following the vaccines from depot pickup to clinic delivery. Regulatory inspectors can verify temperature compliance through the recorded data — supporting regulatory acceptance and quality assurance.

Question 3

What backup systems protect against refrigeration failure?

Accepted Answer

Multiple redundancy layers: primary refrigeration unit operates continuously, backup refrigeration unit on standby with automatic switchover under 5 minutes if primary fails, battery backup supports refrigeration for 4-8 hours during power loss (charging from generator or solar where appropriate), passive thermal mass (insulated walls, frozen gel packs) maintains temperature for 12-24 hours during complete cooling failure, alarm systems alert operator to any temperature excursion. Combined redundancy maintains cold chain through all but the most catastrophic failures.

Question 4

What vaccine transport capacity does the trailer provide?

Accepted Answer

Capacity depends on vaccine packaging and temperature requirements. Standard 40-ft trailer carries approximately 30-50 m³ of refrigerated cargo, equivalent to 5-8 million doses of standard +2°C to +8°C vaccines (assuming WHO standard vial packaging), or 1-2 million doses of -70°C ultra-cold mRNA vaccines (with thicker insulation between doses). Capacity is specified at procurement against the operating programme's typical campaign size.

Question 5

Can the mobile vaccine transport trailer support last-mile delivery to remote sites?

Accepted Answer

Yes. Last-mile delivery from the trailer to immunisation site uses validated cold-chain transport containers (small insulated boxes with frozen gel packs, sized to single-day clinic requirements). The trailer parks at a regional depot or strategic point; immunisation teams collect daily allocation in cold-chain transport containers; vaccines administered at clinics return any unused doses to the trailer. This hub-and-spoke model extends cold-chain reach to immunisation sites without dedicated cold storage.
